/*
 * MiAvio — theme.css
 * --------------------------------------------------------------------------
 * Paleta y tipografía declaradas en CLAUDE.md §14.
 *
 * Notas:
 * - Las fuentes Plus Jakarta Sans deben vivir en static/fonts/ como
 *   .woff2. Si no están presentes, el navegador cae a la pila system-ui.
 *   El paquete real se vendoreará en deploy (Fase 11).
 * - Bootstrap 5 NO se incluye aquí — los estilos son hand-rolled
 *   minimalistas con clases compatibles (.btn, .card, .badge, .form-*)
 *   para que un futuro vendor de Bootstrap sea drop-in.
 * - No hay reglas con !important. Si una vista necesita override,
 *   declarar una clase específica en lugar de pelear con la cascada.
