   Conventions
     - Component classes are flat and prefixed by component (.btn, .btn-primary).
     - State classes start with is- (.is-active, .is-loading, .is-invalid).
     - View-specific CSS lives in /assets/views/<id>.css and must scope every
       selector under .view-<id> (the class the shell puts on the view root).
     - Breakpoints: 640 / 768 / 1024 / 1280 (min-width, mobile first).
