/* ==========================================================================
   ALFRED — Hoja de estilos única
   Objetivo: Android 4.4 (Chromium 30), pantallas táctiles pequeñas y CPUs lentas.

   Reglas de compatibilidad aplicadas:
     - SIN variables CSS (custom properties)  → no soportadas en Chromium 30
     - SIN CSS Grid                            → no soportado
     - SIN animaciones ni transiciones         → ahorro de CPU/GPU
     - SIN degradados ni sombras difusas       → repintado más barato
     - Flexbox con prefijos -webkit-           → cobertura total
     - Tamaños en px y rem simples             → sin clamp()/min()/max()
     - Áreas táctiles >= 48px                  → dedos en pantalla pequeña
