/* =============================================================================
 * public-the-app.css — Pagina /la-app: mockups CSS de alta fidelidad de las pantallas del APK.
 *
 * EXTERNALIZADO desde el bloque `<style>` de `templates/public/the_app.html` (ola F1 del
 * endurecimiento CSP, 2026-07-26). Vivía inline en la plantilla, lo que obligaba
 * a `style-src 'unsafe-inline'` en la Content-Security-Policy: con esa concesión
 * un XSS podía inyectar CSS y exfiltrar datos por selectores + `url()`. Ahora la
 * hoja se sirve de `/static/css/` (mismo origen) y la CSP puede exigir
 * `style-src-elem 'self'` sin ninguna excepción.
 *
 * REGLA: no volver a meter `<style>` en la plantilla — el test
 * `crates/web/tests/csp_no_inline_style_test.rs` lo rompe a propósito.
 * El ORDEN de carga importa: este `<link>` va donde estaba el `<style>`, para
 * que la cascada (quién gana sobre `brand.css`) no cambie de aspecto.
