Color Pipeline Implementer

Use this skill when implementing or adjusting the color pipeline stages. Use the v0.3 docs as the source of truth.

Workflow

1. Read src/planning/spec-v0.3.md and the relevant phase in src/planning/roadmap-v0.3.md.
2. Implement parsing in src/utils/parseColor.ts (hex/rgb to OKLCH, preserve alpha).
3. Implement normalization in src/engine/normalize.ts (clamp L/C/H, defaults, basic validation).
4. Implement base scales and semantic resolution in src/engine/ as per spec ordering.
5. Add focused tests for each stage before moving to the next change.

Guardrails

• Keep logic incremental; avoid skipping phase boundaries.
• Preserve output contracts (ResolvedColor, ColorMeta) as defined in src/types.
• Keep BaseResolvedColor runtime shape stable.
• Prefer small PR-sized changes with clear acceptance criteria.
