+description: Enforce the project's frontend architecture and UI system when implementing or modifying frontend code.
+---
+
+# Frontend System
+
+This skill ensures that all frontend work follows the established UI architecture and design system used in this project.
+
+The system is defined by the real implementation in the codebase, not by external design assumptions.
+
+## Source of truth
+
+The current system is defined by:
+
+- `docs/frontend-system-current-state.md`
+- `components/ui/*`
+- `components/layout/*`
+- `lib/utils.ts`
+- `app/globals.css`
+- `tailwind.config.ts`
+
+These files define the project's UI primitives, tokens, layout rules, and styling system.
+
+## Primitive architecture
+
+All shared UI must originate from the local primitive layer.
+
+Primary primitives live in:
+
+`components/ui`
+
+Examples include:
+
+- Button
+- Card
+- AppCard
+- Input
+- Textarea
+- Select
+- Dialog
+- Sheet
+- Tabs
+- DropdownMenu
+- Accordion
+- Badge
+- Checkbox
+- Table
+- Label
+- Separator
+
+Feature code must reuse these primitives rather than reimplementing their behavior.
+
+If new shared UI behavior is required, extend the primitive layer instead of bypassing it.
+
+## Class composition
+
+Use the project's shared helper:
+
+`cn()`
+
+from:
+
+`lib/utils.ts`
+
+for class composition.
+
+Variant logic should use:
+
+`class-variance-authority (cva)`
+
+when the primitive already exposes variants.
+
+## Allowed libraries
+
+Frontend code may use only the libraries already present in the system.
+
+UI primitives:
+- `@radix-ui/react-*` through local primitives
+
+Styling:
+- `tailwindcss`
+
+Class composition:
+- `class-variance-authority`
+- `clsx`
+- `tailwind-merge`
+
+Motion:
+- `framer-motion`
+- `tailwindcss-animate`
+
+Icons:
+- `lucide-react`
+
+Do not introduce additional UI frameworks or icon libraries.
+
+## Token system
+
+Styling must rely on the semantic token layer defined in:
+
+- `app/globals.css`
+- `tailwind.config.ts`
+
+Prefer semantic tokens over raw color values.
+
+Shared UI must not introduce new arbitrary color values when tokens already exist.
+
+## Radius system
+
+The project uses a shared radius token system.
+
+Approved radius token categories include:
+
+- surface radius
+- nested element radius
+- pill radius
+
+These tokens are mapped in Tailwind and must be used for shared UI.
+
+Shared components should not introduce arbitrary radius values.
+
+## Surface and card system
+
+Shared surfaces should follow the established card system.
+
+Primary shared surfaces originate from:
+
+- `Card`
+- `AppCard`
+
+These primitives define the canonical surface styles used throughout the application.
+
+Feature code should not duplicate card styling directly.
+
+Instead, reuse these primitives or extend them where necessary.
+
+## Layout system
+
+Shared layout constraints should use the project's container system.
+
+The container primitive defines width limits and horizontal padding behavior.
+
+Container variants include categories such as:
+
+- default layout width
+- narrow content width
+- wide layout width
+- admin layout width
+
+Layout code should reuse the container primitive rather than defining ad-hoc layout wrappers.
+
+## Spacing rhythm
+
+The project uses a consistent spacing rhythm.
+
+Common spacing categories include:
+
+- surface padding
+- component internal spacing
+- layout gaps
+- vertical content spacing
+
+Spacing values should remain consistent with the existing system used in primitives and layout components.
+
+Avoid introducing arbitrary spacing values for shared components.
+
+## Motion system
+
+Motion is implemented through two layers.
+
+Custom motion:
+- `framer-motion`
+
+Primitive state transitions:
+- `tailwindcss-animate`
+
+Before introducing new motion patterns, inspect existing motion components and reuse their behavior when possible.
+
+## Icon system
+
+The project uses a single icon library:
+
+- `lucide-react`
+
+Icons should be imported from this library only.
+
+Do not introduce additional icon libraries.
+
+## Arbitrary Tailwind values
+
+Arbitrary Tailwind values are not globally forbidden.
+
+They may be used when required for:
+
+- layout-specific grid definitions
+- rare content sizing constraints
+- typography fitting adjustments
+- one-off layout edge cases not covered by tokens
+
+However, arbitrary values must not replace the shared token system.
+
+They should not be used for shared-system styling when project tokens already exist, especially for categories such as:
+
+- radius
+- colors
+- shadows
+- borders
+- shared surface styling
+
+When arbitrary values are used, they should remain narrow in scope and justified by layout or typography needs.
+
+## Forbidden patterns
+
+The following patterns must be avoided:
+
+- introducing a new UI framework
+- bypassing the local primitive layer when an equivalent primitive already exists
+- creating feature-level implementations of components that already exist in `components/ui`
+- importing Radix primitives directly in feature code when a local wrapper exists
+- introducing raw styling for shared UI surfaces when tokenized styles already exist
+- creating duplicate design systems
+- adding styling abstractions that conflict with the existing token system
+
+## Transitional areas
+
+Some files still contain transitional visual code.
+
+These areas must not be treated as canonical UI system references for new work.
+
+Examples include decorative hero components, experimental visual effects, or legacy route-level styling.
+
+When implementing new UI, prefer primitives and tokens defined in the main system rather than copying patterns from transitional files.
+
+## Implementation guidance for Codex
+
+When implementing frontend code:
+
+1. Inspect existing primitives before writing new UI.
+2. Reuse primitives from `components/ui`.
+3. Prefer semantic tokens over raw styling.
+4. Follow the established radius, surface, spacing, and container systems.
+5. Reuse motion patterns before introducing new ones.
+6. Keep new UI aligned with the current frontend architecture.
+
+If a requested UI does not fit the current primitives, extend the primitive layer rather than bypassing it.

 - 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 `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 re-creating those patterns in feature code.
+- 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 transitional decorative hero files or remaining route-local raw blocks as shared-system primitives.
+- Do not treat route-specific hero visuals or transitional raw blocks as shared-system primitives.
