-# Modern CalDAV Web Client
+# Runway
+## _Passive infrastructure for life's coordination_
+
+![Runway Screenshot](sample.png)
 
 >[!WARNING]
 >This project was entirely vibe coded. It's my first attempt vibe coding anything, but I just sat down one day and realized this was something I've wanted to build for many years, but would just take way too long. With AI, I've been able to lay out the majority  of the app in one long weekend. So proceed at your own risk, but I actually think the app is pretty solid.
 
-A full-stack calendar application built with Rust, featuring a modern web interface for CalDAV calendar management.
+A modern CalDAV web client built with Rust WebAssembly.
 
-## Motivation
+## The Name
 
-While there are many excellent self-hosted CalDAV server implementations (Nextcloud, Radicale, Baikal, etc.), the web client ecosystem remains limited. Existing solutions like [AgenDAV](https://github.com/agendav/agendav) often suffer from outdated interfaces, bugs, and poor user experience. This project aims to provide a modern, fast, and reliable web interface for CalDAV servers.
+Runway embodies the concept of **passive infrastructure** — unobtrusive systems that enable better coordination without getting in the way. Planes can fly and do lots of cool things, but without runways, they can't take off or land. Similarly, calendars and scheduling tools are essential for organizing our lives, but they should not dominate our attention.
+
+The best infrastructure is invisible when working, essential when needed, and enables rather than constrains.

+   npm run install-deps
+   ```
+
+## Running Tests
+
+### Local Development
+- Run all tests: `npm test`
+- Run tests with browser UI: `npm run test:headed`
+- Debug tests: `npm run test:debug`
+- Interactive UI mode: `npm run test:ui`
+
+### Browser-specific Tests
+- Chrome only: `npm run test:chromium`
+- Firefox only: `npm run test:firefox`
+
+### CI/Headless Testing
+Tests automatically run in headless mode when `CI=true` environment variable is set.
+
+## Test Structure
+
+- `tests/auth.spec.ts` - Authentication flow tests
+- `tests/calendar-ui.spec.ts` - General UI interaction tests  
+- `tests/drag-and-drop.spec.ts` - Drag and drop functionality tests
+- `helpers/auth-helpers.ts` - Authentication test utilities
+- `helpers/calendar-helpers.ts` - Calendar interaction utilities
+
+## Environment Variables
+
+For CI and automated testing:
+- `TEST_CALDAV_SERVER` - CalDAV server URL (default: http://localhost:3000/baikal)
+- `TEST_CALDAV_USERNAME` - Test user username (default: testuser)  
+- `TEST_CALDAV_PASSWORD` - Test user password (default: testpass)
+- `CI` - Set to true for headless testing

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+## [Documentation](https://playwright.dev) | [API reference](https://playwright.dev/docs/api/class-playwright)
+
+Playwright is a framework for Web Testing and Automation. It allows testing [Chromium](https://www.chromium.org/Home), [Firefox](https://www.mozilla.org/en-US/firefox/new/) and [WebKit](https://webkit.org/) with a single API. Playwright is built to enable cross-browser web automation that is **ever-green**, **capable**, **reliable** and **fast**.

+
+Headless execution is supported for all browsers on all platforms. Check out [system requirements](https://playwright.dev/docs/intro#system-requirements) for details.
+
+Looking for Playwright for [Python](https://playwright.dev/python/docs/intro), [.NET](https://playwright.dev/dotnet/docs/intro), or [Java](https://playwright.dev/java/docs/intro)?
+
+## Installation
+
+Playwright has its own test runner for end-to-end tests, we call it Playwright Test.
+
+### Using init command
+
+The easiest way to get started with Playwright Test is to run the init command.
+
+```Shell
+# Run from your project's root directory
+npm init playwright@latest
+# Or create a new project
+npm init playwright@latest new-project
+```
+
+This will create a configuration file, optionally add examples, a GitHub Action workflow and a first test example.spec.ts. You can now jump directly to writing assertions section.
+
+### Manually
+
+Add dependency and install browsers.
+
+```Shell
+npm i -D @playwright/test
+# install supported browsers
+npx playwright install
+```
+
+You can optionally install only selected browsers, see [install browsers](https://playwright.dev/docs/cli#install-browsers) for more details. Or you can install no browsers at all and use existing [browser channels](https://playwright.dev/docs/browsers).
+

+* [API reference](https://playwright.dev/docs/api/class-playwright)
+
+## Capabilities
+
+### Resilient • No flaky tests
+
+**Auto-wait**. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - a primary cause of flaky tests.
+
+**Web-first assertions**. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met.
+
+**Tracing**. Configure test retry strategy, capture execution trace, videos and screenshots to eliminate flakes.
+
+### No trade-offs • No limits
+
+Browsers run web content belonging to different origins in different processes. Playwright is aligned with the architecture of the modern browsers and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.
+
+**Multiple everything**. Test scenarios that span multiple tabs, multiple origins and multiple users. Create scenarios with different contexts for different users and run them against your server, all in one test.
+
+**Trusted events**. Hover elements, interact with dynamic controls and produce trusted events. Playwright uses real browser input pipeline indistinguishable from the real user.
+
+Test frames, pierce Shadow DOM. Playwright selectors pierce shadow DOM and allow entering frames seamlessly.
+
+### Full isolation • Fast execution
+
+**Browser contexts**. Playwright creates a browser context for each test. Browser context is equivalent to a brand new browser profile. This delivers full test isolation with zero overhead. Creating a new browser context only takes a handful of milliseconds.
+
+**Log in once**. Save the authentication state of the context and reuse it in all the tests. This bypasses repetitive log-in operations in each test, yet delivers full isolation of independent tests.
+
+### Powerful Tooling
+
+**[Codegen](https://playwright.dev/docs/codegen)**. Generate tests by recording your actions. Save them into any language.
+
+**[Playwright inspector](https://playwright.dev/docs/inspector)**. Inspect page, generate selectors, step through the test execution, see click points and explore execution logs.
+
+**[Trace Viewer](https://playwright.dev/docs/trace-viewer)**. Capture all the information to investigate the test failure. Playwright trace contains test execution screencast, live DOM snapshots, action explorer, test source and many more.
+
+Looking for Playwright for [TypeScript](https://playwright.dev/docs/intro), [JavaScript](https://playwright.dev/docs/intro), [Python](https://playwright.dev/python/docs/intro), [.NET](https://playwright.dev/dotnet/docs/intro), or [Java](https://playwright.dev/java/docs/intro)?
+
+## Examples
+
+To learn how to run these Playwright Test examples, check out our [getting started docs](https://playwright.dev/docs/intro).
+
+#### Page screenshot
+
+This code snippet navigates to Playwright homepage and saves a screenshot.
+
+```TypeScript
+import { test } from '@playwright/test';
+
+test('Page Screenshot', async ({ page }) => {
+  await page.goto('https://playwright.dev/');
+  await page.screenshot({ path: `example.png` });
+});
+```
+
+#### Mobile and geolocation
+
+This snippet emulates Mobile Safari on a device at given geolocation, navigates to maps.google.com, performs the action and takes a screenshot.
+
+```TypeScript
+import { test, devices } from '@playwright/test';
+
+test.use({
+  ...devices['iPhone 13 Pro'],
+  locale: 'en-US',
+  geolocation: { longitude: 12.492507, latitude: 41.889938 },
+  permissions: ['geolocation'],
+})
+
+test('Mobile and geolocation', async ({ page }) => {
+  await page.goto('https://maps.google.com');
+  await page.getByText('Your location').click();
+  await page.waitForRequest(/.*preview\/pwa/);
+  await page.screenshot({ path: 'colosseum-iphone.png' });
+});
+```
+
+#### Evaluate in browser context
+
+This code snippet navigates to example.com, and executes a script in the page context.
+
+```TypeScript
+import { test } from '@playwright/test';
+
+test('Evaluate in browser context', async ({ page }) => {
+  await page.goto('https://www.example.com/');
+  const dimensions = await page.evaluate(() => {
+    return {
+      width: document.documentElement.clientWidth,
+      height: document.documentElement.clientHeight,
+      deviceScaleFactor: window.devicePixelRatio
+    }
+  });
+  console.log(dimensions);
+});
+```
+
+#### Intercept network requests
+
+This code snippet sets up request routing for a page to log all network requests.
+
+```TypeScript
+import { test } from '@playwright/test';
+
+test('Intercept network requests', async ({ page }) => {
+  // Log and continue all network requests
+  await page.route('**', route => {
+    console.log(route.request().url());
+    route.continue();
+  });
+  await page.goto('http://todomvc.com');
+});
+```

+ * * [`AsyncLocalStorage`](https://nodejs.org/docs/latest-v20.x/api/async_context.html#class-asynclocalstorage) tracks async context
+ * * [`process.getActiveResourcesInfo()`](https://nodejs.org/docs/latest-v20.x/api/process.html#processgetactiveresourcesinfo) tracks active resources
+ *
+ * The `node:async_hooks` module provides an API to track asynchronous resources.
+ * It can be accessed using:
+ *
+ * ```js
+ * import async_hooks from 'node:async_hooks';
+ * ```
+ * @experimental

+ * The `node:console` module provides a simple debugging console that is similar to
+ * the JavaScript console mechanism provided by web browsers.
+ *
+ * The module exports two specific components:
+ *
+ * * A `Console` class with methods such as `console.log()`, `console.error()`, and `console.warn()` that can be used to write to any Node.js stream.
+ * * A global `console` instance configured to write to [`process.stdout`](https://nodejs.org/docs/latest-v20.x/api/process.html#processstdout) and
+ * [`process.stderr`](https://nodejs.org/docs/latest-v20.x/api/process.html#processstderr). The global `console` can be used without importing the `node:console` module.
+ *
+ * _**Warning**_: The global console object's methods are neither consistently
+ * synchronous like the browser APIs they resemble, nor are they consistently
+ * asynchronous like all other Node.js streams. See the [`note on process I/O`](https://nodejs.org/docs/latest-v20.x/api/process.html#a-note-on-process-io) for
+ * more information.
+ *
+ * Example using the global `console`:
+ *
+ * ```js
+ * console.log('hello world');
+ * // Prints: hello world, to stdout
+ * console.log('hello %s', 'world');
+ * // Prints: hello world, to stdout
+ * console.error(new Error('Whoops, something bad happened'));
+ * // Prints error message and stack trace to stderr:
+ * //   Error: Whoops, something bad happened
+ * //     at [eval]:5:15
+ * //     at Script.runInThisContext (node:vm:132:18)
+ * //     at Object.runInThisContext (node:vm:309:38)
+ * //     at node:internal/process/execution:77:19
+ * //     at [eval]-wrapper:6:22
+ * //     at evalScript (node:internal/process/execution:76:60)
+ * //     at node:internal/main/eval_string:23:3
+ *
+ * const name = 'Will Robinson';
+ * console.warn(`Danger ${name}! Danger!`);
+ * // Prints: Danger Will Robinson! Danger!, to stderr
+ * ```
+ *
+ * Example using the `Console` class:
+ *
+ * ```js
+ * const out = getStreamSomehow();
+ * const err = getStreamSomehow();
+ * const myConsole = new console.Console(out, err);
+ *
+ * myConsole.log('hello world');
+ * // Prints: hello world, to out
+ * myConsole.log('hello %s', 'world');
+ * // Prints: hello world, to out

+         * The module exports two specific components:
+         *
+         * * A `Console` class with methods such as `console.log()`, `console.error()` and `console.warn()` that can be used to write to any Node.js stream.
+         * * A global `console` instance configured to write to [`process.stdout`](https://nodejs.org/docs/latest-v20.x/api/process.html#processstdout) and
+         * [`process.stderr`](https://nodejs.org/docs/latest-v20.x/api/process.html#processstderr). The global `console` can be used without importing the `node:console` module.
+         *
+         * _**Warning**_: The global console object's methods are neither consistently
+         * synchronous like the browser APIs they resemble, nor are they consistently
+         * asynchronous like all other Node.js streams. See the [`note on process I/O`](https://nodejs.org/docs/latest-v20.x/api/process.html#a-note-on-process-io) for
+         * more information.
+         *
+         * Example using the global `console`:
+         *
+         * ```js
+         * console.log('hello world');
+         * // Prints: hello world, to stdout
+         * console.log('hello %s', 'world');
+         * // Prints: hello world, to stdout
+         * console.error(new Error('Whoops, something bad happened'));
+         * // Prints error message and stack trace to stderr:
+         * //   Error: Whoops, something bad happened
+         * //     at [eval]:5:15
+         * //     at Script.runInThisContext (node:vm:132:18)

+         * // Prints: Danger Will Robinson! Danger!, to stderr
+         * ```

+ * convenience, but as long as the name is known it can be acquired anywhere.
+ *
+ * If you intend for your module to produce diagnostics data for others to

+ * channels are used along with the shape of the message data. Channel names
+ * should generally include the module name to avoid collisions with data from
+ * other modules.

+ * The `node:dns` module enables name resolution. For example, use it to look up IP
+ * addresses of host names.
+ *
+ * Although named for the [Domain Name System (DNS)](https://en.wikipedia.org/wiki/Domain_Name_System), it does not always use the
+ * DNS protocol for lookups. {@link lookup} uses the operating system
+ * facilities to perform name resolution. It may not need to perform any network
+ * communication. To perform name resolution the way other applications on the same
+ * system do, use {@link lookup}.
+ *
+ * ```js
+ * import dns from 'node:dns';
+ *
+ * dns.lookup('example.org', (err, address, family) => {
+ *   console.log('address: %j family: IPv%s', address, family);
+ * });
+ * // address: "93.184.216.34" family: IPv4
+ * ```
+ *
+ * All other functions in the `node:dns` module connect to an actual DNS server to
+ * perform name resolution. They will always use the network to perform DNS
+ * queries. These functions do not use the same set of configuration files used by {@link lookup} (e.g. `/etc/hosts`). Use these functions to always perform
+ * DNS queries, bypassing other name-resolution facilities.
+ *
+ * ```js
+ * import dns from 'node:dns';
+ *
+ * dns.resolve4('archive.org', (err, addresses) => {
+ *   if (err) throw err;
+ *
+ *   console.log(`addresses: ${JSON.stringify(addresses)}`);
+ *
+ *   addresses.forEach((a) => {

+ *       }

+ * event-driven architecture in which certain kinds of objects (called "emitters")
+ * emit named events that cause `Function` objects ("listeners") to be called.
+ *
+ * For instance: a `net.Server` object emits an event each time a peer
+ * connects to it; a `fs.ReadStream` emits an event when the file is opened;
+ * a `stream` emits an event whenever data is available to be read.
+ *
+ * All objects that emit events are instances of the `EventEmitter` class. These
+ * objects expose an `eventEmitter.on()` function that allows one or more
+ * functions to be attached to named events emitted by the object. Typically,
+ * event names are camel-cased strings but any valid JavaScript property key
+ * can be used.
+ *
+ * When the `EventEmitter` object emits an event, all of the functions attached
+ * to that specific event are called _synchronously_. Any values returned by the
+ * called listeners are _ignored_ and discarded.
+ *
+ * The following example shows a simple `EventEmitter` instance with a single
+ * listener. The `eventEmitter.on()` method is used to register listeners, while
+ * the `eventEmitter.emit()` method is used to trigger the event.
+ *
+ * ```js
+ * import { EventEmitter } from 'node:events';
+ *
+ * class MyEmitter extends EventEmitter {}
+ *
+ * const myEmitter = new MyEmitter();
+ * myEmitter.on('event', () => {
+ *   console.log('an event occurred!');
+ * });
+ * myEmitter.emit('event');
+ * ```
+ * @see [source](https://github.com/nodejs/node/blob/v20.13.1/lib/events.js)

+ *
+ * [Punycode](https://tools.ietf.org/html/rfc3492) is a character encoding scheme defined by RFC 3492 that is
+ * primarily intended for use in Internationalized Domain Names. Because host
+ * names in URLs are limited to ASCII characters only, Domain Names that contain
+ * non-ASCII characters must be converted into ASCII using the Punycode scheme.

+ * to `'example.com'`) is represented by Punycode as the ASCII string `'xn--fsq.com'`.
+ *
+ * The `punycode` module provides a simple implementation of the Punycode standard.
+ *
+ * The `punycode` module is a third-party dependency used by Node.js and

+     * });
+     * ```
+     *
+     * ## Example: Read file stream line-by-Line
+     *
+     * A common use case for `readline` is to consume an input file one line at a
+     * time. The easiest way to do so is leveraging the `fs.ReadStream` API as
+     * well as a `for await...of` loop:
+     *
+     * ```js
+     * import fs from 'node:fs';
+     * import readline from 'node:readline';
+     *
+     * async function processLineByLine() {
+     *   const fileStream = fs.createReadStream('input.txt');
+     *
+     *   const rl = readline.createInterface({
+     *     input: fileStream,
+     *     crlfDelay: Infinity,
+     *   });
+     *   // Note: we use the crlfDelay option to recognize all instances of CR LF
+     *   // ('\r\n') in input.txt as a single line break.
+     *
+     *   for await (const line of rl) {
+     *     // Each line in input.txt will be successively available here as `line`.
+     *     console.log(`Line from file: ${line}`);
+     *   }
+     * }
+     *
+     * processLineByLine();
+     * ```
+     *
+     * Alternatively, one could use the `'line'` event:
+     *
+     * ```js
+     * import fs from 'node:fs';
+     * import readline from 'node:readline';
+     *
+     * const rl = readline.createInterface({
+     *   input: fs.createReadStream('sample.txt'),
+     *   crlfDelay: Infinity,
+     * });
+     *
+     * rl.on('line', (line) => {
+     *   console.log(`Line from file: ${line}`);
+     * });
+     * ```
+     *
+     * Currently, `for await...of` loop can be a bit slower. If `async` / `await` flow and speed are both essential, a mixed approach can be applied:
+     *
+     * ```js
+     * import { once } from 'node:events';
+     * import { createReadStream } from 'node:fs';
+     * import { createInterface } from 'node:readline';
+     *
+     * (async function processLineByLine() {
+     *   try {
+     *     const rl = createInterface({
+     *       input: createReadStream('big-file.txt'),
+     *       crlfDelay: Infinity,
+     *     });
+     *
+     *     rl.on('line', (line) => {
+     *       // Process the line.
+     *     });
+     *

+/**
+ * This feature allows the distribution of a Node.js application conveniently to a
+ * system that does not have Node.js installed.
+ *
+ * Node.js supports the creation of [single executable applications](https://github.com/nodejs/single-executable) by allowing
+ * the injection of a blob prepared by Node.js, which can contain a bundled script,
+ * into the `node` binary. During start up, the program checks if anything has been
+ * injected. If the blob is found, it executes the script in the blob. Otherwise
+ * Node.js operates as it normally does.
+ *
+ * The single executable application feature currently only supports running a
+ * single embedded script using the `CommonJS` module system.
+ *
+ * Users can create a single executable application from their bundled script
+ * with the `node` binary itself and any tool which can inject resources into the
+ * binary.
+ *
+ * Here are the steps for creating a single executable application using one such
+ * tool, [postject](https://github.com/nodejs/postject):
+ *
+ * 1. Create a JavaScript file:
+ * ```bash
+ * echo 'console.log(`Hello, ${process.argv[2]}!`);' > hello.js
+ * ```
+ * 2. Create a configuration file building a blob that can be injected into the
+ * single executable application (see `Generating single executable preparation blobs` for details):
+ * ```bash
+ * echo '{ "main": "hello.js", "output": "sea-prep.blob" }' > sea-config.json
+ * ```
+ * 3. Generate the blob to be injected:
+ * ```bash
+ * node --experimental-sea-config sea-config.json
+ * ```
+ * 4. Create a copy of the `node` executable and name it according to your needs:
+ *    * On systems other than Windows:
+ * ```bash
+ * cp $(command -v node) hello
+ * ```
+ *    * On Windows:
+ * ```text
+ * node -e "require('fs').copyFileSync(process.execPath, 'hello.exe')"
+ * ```
+ * The `.exe` extension is necessary.
+ * 5. Remove the signature of the binary (macOS and Windows only):
+ *    * On macOS:
+ * ```bash
+ * codesign --remove-signature hello
+ * ```
+ *    * On Windows (optional):
+ * [signtool](https://learn.microsoft.com/en-us/windows/win32/seccrypto/signtool) can be used from the installed [Windows SDK](https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/).
+ * If this step is
+ * skipped, ignore any signature-related warning from postject.
+ * ```powershell
+ * signtool remove /s hello.exe
+ * ```
+ * 6. Inject the blob into the copied binary by running `postject` with
+ * the following options:
+ *    * `hello` / `hello.exe` \- The name of the copy of the `node` executable
+ *    created in step 4.
+ *    * `NODE_SEA_BLOB` \- The name of the resource / note / section in the binary
+ *    where the contents of the blob will be stored.
+ *    * `sea-prep.blob` \- The name of the blob created in step 1.
+ *    * `--sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2` \- The [fuse](https://www.electronjs.org/docs/latest/tutorial/fuses) used by the Node.js project to detect if a file has been
+ * injected.
+ *    * `--macho-segment-name NODE_SEA` (only needed on macOS) - The name of the
+ *    segment in the binary where the contents of the blob will be
+ *    stored.
+ * To summarize, here is the required command for each platform:
+ *    * On Linux:
+ *    ```bash
+ *    npx postject hello NODE_SEA_BLOB sea-prep.blob \
+ *        --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
+ *    ```
+ *    * On Windows - PowerShell:
+ *    ```powershell
+ *    npx postject hello.exe NODE_SEA_BLOB sea-prep.blob `
+ *        --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
+ *    ```
+ *    * On Windows - Command Prompt:
+ *    ```text
+ *    npx postject hello.exe NODE_SEA_BLOB sea-prep.blob ^
+ *        --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
+ *    ```
+ *    * On macOS:
+ *    ```bash
+ *    npx postject hello NODE_SEA_BLOB sea-prep.blob \
+ *        --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 \
+ *        --macho-segment-name NODE_SEA
+ *    ```
+ * 7. Sign the binary (macOS and Windows only):
+ *    * On macOS:
+ * ```bash
+ * codesign --sign - hello
+ * ```
+ *    * On Windows (optional):
+ * A certificate needs to be present for this to work. However, the unsigned
+ * binary would still be runnable.
+ * ```powershell
+ * signtool sign /fd SHA256 hello.exe
+ * ```
+ * 8. Run the binary:
+ *    * On systems other than Windows
+ * ```console
+ * $ ./hello world
+ * Hello, world!
+ * ```
+ *    * On Windows
+ * ```console
+ * $ .\hello.exe world
