Scoped CSS and Computed Styles
How FLIN's scoped CSS system prevents style leakage between components and enables computed styles that react to state changes -- combining CSS isolation with runtime dynamism.
Guards: Declarative Security for Routes
How FLIN's guard system provides declarative, composable access control for routes -- auth, roles, rate limiting, CSRF, IP whitelists, and time-based access in single-line declarations.
