## 1. Install

```bash
npx rahman-resources add marketing-chrome
# alias: npx rr add marketing-chrome
```

The CLI copies `frontend/slices/marketing-chrome/` into your project + augments `.env.example` + installs npm deps automatically. Run it from your project root.

## 2. What it ships

- shadcn primitives: `button`, `sheet`, `separator`

## 3. Wire it up

Run `npx rr add marketing-chrome`. Feed MarketingHeader { brand, nav[], cta, layout } and MarketingFooter { brand, columns[], social[], legal[], layout }. Header layout split is the default marketing pattern; footer columns for full sites, slim for single-pagers.

## Rules of engagement

- shadcn-only UI primitives. No raw `<button>` / `<dialog>` / native date or file inputs.
- 200-line hard cap per source file (extract neighbours when over).
- All Convex queries hit an index (`.withIndex(...)`); never bare `.collect()`.
- Public mutations/queries declare `args:` validators + authz.
