# Homepage Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Build a cinematic, scroll-driven project homepage for Understand Anything using Astro, deployed to GitHub Pages via `gh-pages` branch.

**Architecture:** Astro SSG project in `homepage/` on main. Self-hosted fonts (DM Serif Display, Inter, JetBrains Mono) with robust fallbacks. Pure CSS animations triggered by `IntersectionObserver`. GitHub Actions workflow builds and deploys to `gh-pages` on push.

**Tech Stack:** Astro 5, CSS custom properties, vanilla JS, GitHub Actions

**Design doc:** `docs/plans/2026-03-15-homepage-design.md`

---

### Task 1: Scaffold Astro Project

**Files:**
- Create: `homepage/package.json`
- Create: `homepage/astro.config.mjs`
- Create: `homepage/tsconfig.json`
- Create: `homepage/src/pages/index.astro` (placeholder)
- Create: `homepage/src/layouts/Layout.astro` (placeholder)
- Create: `homepage/public/.gitkeep`

**Step 1: Initialize Astro project**

```bash
cd /Users/yuxianglin/Desktop/opensource/Understand-Anything
mkdir -p homepage
cd homepage
pnpm create astro@latest . -- --template minimal --no-install --no-git --typescript strict
```

If the interactive prompt blocks, create files manually instead.

**Step 2: Configure Astro for GitHub Pages**

Edit `homepage/astro.config.mjs`:

```js
import { defineConfig } from 'astro/config';

export default defineConfig({
  site: 'https://lum1104.github.io',
  base: '/Understand-Anything',
});
```

**Step 3: Verify the project builds**

```bash
cd /Users/yuxianglin/Desktop/opensource/Understand-Anything/homepage
pnpm install
pnpm build
```

Expected: Build succeeds, `dist/` directory created.

**Step 4: Commit**

```bash
git add homepage/
git commit -m "feat(homepage): scaffold Astro project with GitHub Pages config"
```

### Task 2: Self-Host Fonts & Base CSS

**Files:**
- Create: `homepage/public/fonts/DMSerifDisplay-Regular.woff2`
- Create: `homepage/public/fonts/Inter-Regular.woff2`
- Create: `homepage/public/fonts/Inter-SemiBold.woff2`
- Create: `homepage/public/fonts/JetBrainsMono-Regular.woff2`
- Create: `homepage/src/styles/global.css`

**Step 1: Download font files**

Download the WOFF2 files from Google Fonts API (or fontsource). Place them in `homepage/public/fonts/`. Required files:
- DM Serif Display Regular (woff2)
- Inter Regular + SemiBold (woff2)
- JetBrains Mono Regular (woff2)

Use curl to download from fontsource CDN or Google Fonts CSS API. Example:

```bash
mkdir -p homepage/public/fonts
# Download from fontsource (reliable CDN)
curl -L "https://cdn.jsdelivr.net/fontsource/fonts/dm-serif-display@latest/latin-400-normal.woff2" -o homepage/public/fonts/DMSerifDisplay-Regular.woff2
curl -L "https://cdn.jsdelivr.net/fontsource/fonts/inter@latest/latin-400-normal.woff2" -o homepage/public/fonts/Inter-Regular.woff2
curl -L "https://cdn.jsdelivr.net/fontsource/fonts/inter@latest/latin-600-normal.woff2" -o homepage/public/fonts/Inter-SemiBold.woff2
curl -L "https://cdn.jsdelivr.net/fontsource/fonts/jetbrains-mono@latest/latin-400-normal.woff2" -o homepage/public/fonts/JetBrainsMono-Regular.woff2
```

If download fails, try alternative URLs or use `npx fontsource` to install locally.

**Step 2: Create global CSS with design tokens and font-face declarations**

Create `homepage/src/styles/global.css`:

```css
/* Font declarations — self-hosted, no external CDN dependency */
@font-face {
  font-family: 'DM Serif Display';
  src: url('/Understand-Anything/fonts/DMSerifDisplay-Regular.woff2') format('woff2');
  font-weight: 400;
  font-style: normal;
  font-display: swap;
}

@font-face {
  font-family: 'Inter';
  src: url('/Understand-Anything/fonts/Inter-Regular.woff2') format('woff2');
  font-weight: 400;
  font-style: normal;
  font-display: swap;
}

@font-face {
  font-family: 'Inter';
  src: url('/Understand-Anything/fonts/Inter-SemiBold.woff2') format('woff2');
  font-weight: 600;
  font-style: normal;
  font-display: swap;
}

@font-face {
  font-family: 'JetBrains Mono';
  src: url('/Understand-Anything/fonts/JetBrainsMono-Regular.woff2') format('woff2');
  font-weight: 400;
  font-style: normal;
  font-display: swap;
}

/* Design tokens */
:root {
  --bg: #0a0a0a;
  --surface: #141414;
  --border: #1a1a1a;
  --accent: #d4a574;
  --accent-glow: rgba(212, 165, 116, 0.15);
  --text: #e8e2d8;
  --text-muted: #8a8578;

  --font-heading: 'DM Serif Display', Georgia, 'Times New Roman', serif;
  --font-body: 'Inter', -apple-system, BlinkMacSystemFont, 'Segoe UI', sans-serif;
  --font-code: 'JetBrains Mono', 'SF Mono', 'Cascadia Code', 'Fira Code', monospace;
}

/* Reset & base */
*, *::before, *::after {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

html {
  scroll-behavior: smooth;
}

body {
  font-family: var(--font-body);
  background-color: var(--bg);
  color: var(--text);
  line-height: 1.6;
  -webkit-font-smoothing: antialiased;
  overflow-x: hidden;
}

/* Noise texture overlay */
body::before {
  content: '';
  position: fixed;
  inset: 0;
  pointer-events: none;
  z-index: 9999;
  opacity: 0.03;
  background-image: url("data:image/svg+xml,%3Csvg viewBox='0 0 256 256' xmlns='http://www.w3.org/2000/svg'%3E%3Cfilter id='noise'%3E%3CfeTurbulence type='fractalNoise' baseFrequency='0.9' numOctaves='4' stitchTiles='stitch'/%3E%3C/filter%3E%3Crect width='100%25' height='100%25' filter='url(%23noise)'/%3E%3C/svg%3E");
}

/* Scroll-reveal animation */
@keyframes fadeSlideUp {
  from {
    opacity: 0;
    transform: translateY(30px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

.reveal {
  opacity: 0;
}

.reveal.visible {
  animation: fadeSlideUp 0.8s ease-out forwards;
}

/* Stagger delays for feature cards */
.reveal-delay-1 { animation-delay: 0.1s; }
.reveal-delay-2 { animation-delay: 0.25s; }
.reveal-delay-3 { animation-delay: 0.4s; }

a {
  color: var(--accent);
  text-decoration: none;
}

a:hover {
  text-decoration: underline;
}
```

**Step 3: Import global CSS in Layout**

Update `homepage/src/layouts/Layout.astro`:

```astro
---
interface Props {
  title: string;
}

const { title } = Astro.props;
---

<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="description" content="Turn any codebase into an interactive knowledge graph you can explore, search, and learn from." />
    <link rel="icon" type="image/svg+xml" href="/Understand-Anything/favicon.svg" />
    <title>{title}</title>
  </head>
  <body>
    <slot />
  </body>
</html>

<style is:global>
  @import '../styles/global.css';
</style>
```

**Step 4: Build and verify fonts load**

```bash
cd /Users/yuxianglin/Desktop/opensource/Understand-Anything/homepage
pnpm build
```

Expected: Build succeeds. Check `dist/fonts/` contains the woff2 files.

**Step 5: Commit**

```bash
git add homepage/public/fonts/ homepage/src/styles/global.css homepage/src/layouts/Layout.astro
git commit -m "feat(homepage): add self-hosted fonts and design token CSS"
```

```astro
---
import Layout from '../layouts/Layout.astro';
import Nav from '../components/Nav.astro';
import Hero from '../components/Hero.astro';
import Showcase from '../components/Showcase.astro';
import Features from '../components/Features.astro';
import Install from '../components/Install.astro';
import Footer from '../components/Footer.astro';
---

<Layout title="Understand Anything — Turn any codebase into a knowledge graph">
  <Nav />
  <Hero />
  <Showcase />
  <Features />
  <Install />
  <Footer />
</Layout>

<script>
  const observer = new IntersectionObserver(
    (entries) => {
      entries.forEach((entry) => {
        if (entry.isIntersecting) {
          entry.target.classList.add('visible');
          observer.unobserve(entry.target);
        }
      });
    },
    { threshold: 0.15 }
  );

  document.querySelectorAll('.reveal').forEach((el) => observer.observe(el));
</script>
```

**Step 2: Build and verify the full page**

```

**Step 5: Configure GitHub Pages**

After pushing to main, go to GitHub repo Settings → Pages → Source: select "GitHub Actions". The workflow will auto-deploy on the next push that touches `homepage/`.
