## 1. Install

```bash
npx rahman-resources add theme-presets
# alias: npx rr add theme-presets
```

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

## 2. What it ships

- npm: `next-themes`
- shadcn primitives: `button`, `popover`

## 3. Wire it up

Run `npx rr add theme-presets` (registry-data.json ships inside the slice — no separate public/ copy step). Wrap your tree once with `<ThemePresetProvider>` (inside next-themes' ThemeProvider). Mount `<ThemePresetSwitcher />` anywhere in your header / sidebar / settings — one component handles light/dark/system + preset palette. Wrap dashboard with `<ThemeColorSync>` if you need live tweakcn variable preview on inner routes. Deeply-nested consumers read state via `useThemePreset()` (returns `{ presetName, registry, setPreset, preview, restore, isReady }`). For lower-level access: `applyTweakcnPreset(name)`, `previewTweakcnPreset(name)`, `restoreTweakcnPreset()`, `groupTweakcnPresets(items)`, `tweakcnSwatches(preset)` all exported from `@/features/theme-presets`. To rename localStorage key, fork `STORAGE_KEY` in `lib/tweakcn/types.ts`.

## 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.

The agent will fetch /llms.txt for the full ruleset and use /api/knowledge for the JSON catalog.
