chore: merge prototyping branch

Most of the core configuration is done, and now the project has a reasonable path for the future. More features will be added and refactored in future pull requests and commits.

+# create-svelte
+
+Everything you need to build a Svelte project, powered by [`create-svelte`](https://github.com/sveltejs/kit/tree/master/packages/create-svelte).
+
+## Creating a project
+
+If you're seeing this, you've probably already done this step. Congrats!
+
+```bash
+# create a new project in the current directory
+npm create svelte@latest
+
+# create a new project in my-app
+npm create svelte@latest my-app
+```
+
+## Developing
+
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+
+```bash
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```
+
+## Building
+
+To create a production version of your app:
+
+```bash
+npm run build
+```
+
+You can preview the production build with `npm run preview`.
+
+> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.

+	<h1>How to play Sverdle</h1>
+
+	<p>
+		Sverdle is a clone of <a href="https://www.nytimes.com/games/wordle/index.html">Wordle</a>, the
+		word guessing game. To play, enter a five-letter English word. For example:
+	</p>
+
+	<div class="example">
+		<span class="close">r</span>
+		<span class="missing">i</span>
+		<span class="close">t</span>
+		<span class="missing">z</span>
+		<span class="exact">y</span>
+	</div>
+
+	<p>
+		The <span class="exact">y</span> is in the right place. <span class="close">r</span> and
+		<span class="close">t</span>
+		are the right letters, but in the wrong place. The other letters are wrong, and can be discarded.
+		Let's make another guess:
+	</p>
+
+	<div class="example">
+		<span class="exact">p</span>
+		<span class="exact">a</span>
+		<span class="exact">r</span>
+		<span class="exact">t</span>
+		<span class="exact">y</span>
+	</div>
+
+	<p>This time we guessed right! You have <strong>six</strong> guesses to get the word.</p>
+
+	<p>
+		Unlike the original Wordle, Sverdle runs on the server instead of in the browser, making it
+		impossible to cheat. It uses <code>&lt;form&gt;</code> and cookies to submit data, meaning you can
+		even play with JavaScript disabled!
