A system, not a component shelf
Agala UI treats visual consistency and behavioral consistency as the same engineering problem. Buttons and inputs matter, but so do focus movement, overlay positioning, empty states, selection models, and the way a theme crosses package boundaries.
The library is organized around small typed contracts and composable behavior. That creates a stable foundation for product work without forcing every interface into one rigid visual expression.
The hard part
Scheduling pushed the system beyond isolated controls. Calendar month, week, day, and list views had to share date logic while supporting slot selection and different information densities. The result became a test of the entire design system: tokens, layout, state, keyboard behavior, and API shape working together.
What it demonstrates
- Product-minded API design for frontend infrastructure
- Accessible interaction patterns rather than visual-only components
- Package architecture with a zero-dependency core
- Long-term thinking about theme contracts and evolution
