- `Container`
  - `px-4 sm:px-6 lg:px-8`

## 9. Current motion rules in use

Primary motion library:

- `framer-motion`

State animation utility layer:

- `tailwindcss-animate`

Current motion patterns:

- reveal-on-scroll wrapper
  - `components/motion-fade.tsx`
  - `initial: { opacity: 0, y: 20 }`
  - `whileInView: { opacity: 1, y: 0 }`
  - `transition: { duration: 0.45, ease: "easeOut" }`
- shared overlay open/close classes
  - `dialog`
  - `sheet`
  - `select`
  - `dropdown-menu`
  - `accordion`
- animated nav active pill and mobile menu
  - `components/layout/site-header.tsx`

## 10. Current icon rules in use

Current icon library:

- `lucide-react`

Current shared rule:

Icons are imported directly from `lucide-react` and passed through local primitives or feature components.

Examples:

- `components/ui/dialog.tsx`
- `components/ui/select.tsx`
- `components/layout/site-header.tsx`
- `components/theme-toggle.tsx`
- `components/root/portfolio-project-form.tsx`

No second React icon library is currently present in `package.json`.

## 11. Current forbidden drift or remaining transitional areas, if any

The shared primitive system is currently tokenized.

Remaining transitional areas still present in the codebase:

- public hero / atmospheric visuals still use raw gradients and `rgba(...)` decorative backgrounds
  - `components/layout/home-hero.tsx`
  - `components/layout/site-ambient-backdrop.tsx`
  - `components/layout/hero-atmosphere.tsx`
  - `components/layout/site-logo.tsx`
- `coming-soon` page still uses older raw translucent chrome styles
  - `app/[locale]/coming-soon/page.tsx`
- some public route-level content blocks still use direct local classes instead of shared primitive wrappers
  - `app/[locale]/(site)/portfolio/page.tsx`
  - `app/[locale]/(site)/portfolio/[slug]/page.tsx`
- one preview block in site settings still uses a custom dark preview surface
  - `components/root/site-settings-form.tsx`
  - `bg-slate-950`
  - `text-white/55`
  - `text-white/60`

These files exist in the current codebase and should be treated as remaining transitional areas, not as shared-system rules.

## 12. Codex rules derived from the current system

- Use `components/ui` as the primitive source of truth.
- Use `cn()` from `lib/utils.ts` for class composition.
- Use `cva()` where the primitive already exposes variants.
- Use semantic tokens already defined in `app/globals.css` and mapped in `tailwind.config.ts`.
- Use `Card` for the base surface:
  - `rounded-surface border border-border/80 bg-card text-card-foreground shadow-card`
- Use `AppCard` when feature code needs explicit shared surface levels.
- Use `AppCard level={1}` for primary card surfaces.
- Use `AppCard level={2}` for nested panels and inner blocks.
- Use `AppCard level={3}` for elevated grouped panels.
- Use `rounded-surface`, `rounded-nested`, and `rounded-pill` as the shared radius system.
- Use `Input`, `Textarea`, `Select`, `Dialog`, `Sheet`, and `Tabs` from `components/ui` instead of re-creating those patterns in feature code.
- Use `Container` for width and horizontal padding rules.
- Use `lucide-react` for icons.
- Use `framer-motion` for custom motion and `tailwindcss-animate` for primitive state transitions.
- Do not treat transitional decorative hero files or remaining route-local raw blocks as shared-system primitives.
