PettyUI/packages/core/tests/pagination.test.ts
Mats Bosson 168b5642d0 All components, schemas, tests, MCP, and showcase
- 51 headless Web Components (45 core + 6 animation)
- Shared helpers: emit(), part(), listen(), wireLabel(), initialValue()
- Zero `new CustomEvent` or `static #counter` — all use shared utils
- Zod schemas for all 44 core components
- MCP package with discover, inspect, compose, validate tools
- Showcase with Aperture Science theme, M3 Expressive motion
- 81 tests passing, TypeScript strict mode clean
- Signals (~500B), SPA router (~400B), zero dependencies
