# Task 12 — Landing page

**Agent**: `page-migrator` · **Model**: MiniMax-M3 **Depends on**: 03, 08 ·
**Parallel with**: 13, 14, 17 **Worktree**:
`.agents/scripts/worktree.sh start 12 page-landing`

## Goal

`index.html` → `src/pages/index.astro`. Smallest page migration; sets the
pattern the other page tasks follow.

## Steps

Snapshot first (task 03 baseline exists — diff against it). Then compose from
`RouteCard` + `GridGroup`, move copy to the `chapters` collection, port
`landing.css` into component styles.

## Hard constraints

- URL stays `/ai-for-dummies/` exactly
- **Zero JS** — this page has none today
- `<title>`, `<meta name="description">`, viewport preserved
- Internal links via `import.meta.env.BASE_URL`, never hand-written absolute

## Done when

- [ ] `diff .agents/snapshots/index.txt <(snapshot of dist)` empty
- [ ] Screenshots match at four widths
- [ ] Built page ships **0 bytes** of JS
- [ ] `.agents/checklists/before-page.md` complete; `pnpm run gate` green
