## Reuse (mandatory before build)

Follow `velin-reuse-gate` (BP-R01…R04):

1. **SEARCH** existing VelinStyle skills, components/Web Components, utilities, tokens, and patterns.
2. **EXISTING?** If a fit exists, document it.
3. **COMPATIBLE?** If yes → **REUSE** (or EXTEND). If no → document the incompatibility.
4. **NEW** only with evidenced gap — never "create because needed".
5. Skipping reuse on non-greenfield work → **STOP** (SR-12).

## Workflow
1. SEARCH theme packs/tokens in project.
2. Apply only existing tokens (BP-T01).
3. Recommend contrast check after change (BP-T02).

## Anti-patterns
- Nearest-color mapping; raising SAFE_REWRITE; rewrite Apply from theme skill.
