/* ==========================================================================
     Becure — estilo "Nocturne" (design_handoff_nocturne_restyle, dirección
     Fiel). Base oscura gris azulada, Inter 500, radios de 8px y un acento
     violeta que se usa en líneas y brillos, nunca como relleno.

     Restricciones que este archivo respeta (ver index.html y
     backend/tests/test_frontend_csp.py):
     - CSP 'self': la fuente (fonts/, build oficial de Inter 4.1.1, subset
       latino) y los íconos (icons/sprite.svg, Phosphor 2.1.1) son archivos
       locales; nada de Google Fonts ni CDNs.
     - app.js lee --sev-info|low|medium|high|critical con getComputedStyle
       (sevColor): esas variables existen en los dos temas.
