# Frontend System Current State

## 1. UI primitive source of truth

The current primitive source of truth is the local

`components/ui`

layer.

Current core primitive files:

- `components/ui/button.tsx`
- `components/ui/card.tsx`
- `components/ui/app-card.tsx`
- `components/ui/input.tsx`
- `components/ui/textarea.tsx`
- `components/ui/select.tsx`
- `components/ui/dialog.tsx`
- `components/ui/sheet.tsx`
- `components/ui/tabs.tsx`
- `components/ui/dropdown-menu.tsx`
- `components/ui/accordion.tsx`
- `components/ui/badge.tsx`
- `components/ui/checkbox.tsx`
- `components/ui/table.tsx`
- `components/ui/label.tsx`
- `components/ui/separator.tsx`

Feature code currently imports these local primitives rather than importing Radix primitives directly.

## 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 }}`

## 10. Current icon rules in use

Current icon library:

- `lucide-react`

Current rule:

icons are imported directly from

`lucide-react`

and used 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 present in:

- `package.json`

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

The shared primitive layer is currently tokenized.

Remaining transitional or non-shared drift still present in the codebase:

- public atmospheric and hero visuals still use route-specific raw gradients and `rgba(...)`
  - `components/layout/home-hero.tsx`
  - `components/layout/site-ambient-backdrop.tsx`
  - `components/layout/hero-atmosphere.tsx`
  - `components/layout/site-logo.tsx`
- `coming-soon` still uses older translucent raw chrome rules
  - `app/[locale]/coming-soon/page.tsx`
- some public route-level content blocks still use route-local classes instead of shared primitives
  - `app/[locale]/(site)/portfolio/page.tsx`
  - `app/[locale]/(site)/portfolio/[slug]/page.tsx`
- one custom dark preview surface remains in current admin code
  - `components/root/site-settings-form.tsx`
  - `bg-slate-950`
  - `text-white/55`
  - `text-white/60`
- some admin and public cards still use `Card` with local class overrides instead of `AppCard`
  - `app/root/page.tsx`
  - `components/dashboard/dashboard-card.tsx`

These are current areas in the repository, but they are not the 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 semantic tokens already defined in `app/globals.css` and mapped in `tailwind.config.ts`.
- Use `Card` as the base surface primitive.
- 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 rebuilding 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 route-specific hero visuals or transitional raw blocks as shared-system primitives.
