Initialize Design System

You are initializing the design-to-code workflow for this project. Your job is to deeply understand the existing codebase's design patterns and produce a design-tokens.json file at .claude/d2c/design-tokens.json.

Non-negotiables

These rules hold across every phase of this skill. No exceptions.

1. Design tokens MUST be loaded before any decision. Read .claude/d2c/design-tokens.json. If it is missing, unreadable, or has d2c_schema_version < 1, STOP AND ASK the user to run /d2c-init (or /d2c-init --force if outdated).
2. NEVER use a library outside preferred_libraries.<category>.selected. The user explicitly chose which library to use for each capability. NEVER substitute an installed-but-not-selected library. If the design requires a capability not covered by preferred_libraries, STOP AND ASK.
3. NEVER hardcode color, spacing, typography, shadow, or radius values. Every visual value MUST reference a design token from design-tokens.json. No raw hex, no magic numbers, no exceptions.
4. MUST reuse existing components when an existing component can serve the need. Check the components array in design-tokens.json before creating anything new. If an existing component can do the job, MUST use it.
5. MUST follow project conventions when confidence > 0.6 and value ≠ "mixed". Project conventions (declaration style, export style, type definitions, import ordering, file naming, CSS wrapper, barrel exports, props pattern) override framework defaults.
6. NEVER re-decide a locked component or token. Read decisions.lock.json from the IR run directory at the start of every phase after Phase 2. Only nodes with status: "failed" may have their component choice or token mapping changed. If a locked decision must change, STOP AND ASK.

When any rule is ambiguous, STOP AND ASK — do not guess.
