Read relevant context (AGENTS.md, PLAN.md, CONTRIBUTING.md). 2. Keep shared code framework-agnostic (no React). 3. Prefer explicit types and small pure utilities. ## Key Paths - `packages/shared/types/` - `packages/shared/utils/` - `packages/shared/constants/` ## Output Expectations - No React dependencies - Pure functions with explicit types ## Testing - Vitest for utilities
