   SISTEMA DE COLORES LYTIKS — DOS CAPAS

   CAPA 1 — TEMA (identidad visual, navegacion, marca)
     --color-primary, --color-accent, --color-bg, --color-surface...
     Cambian con el tema. Definen la personalidad visual de la app.

   CAPA 2 — SEMANTICA (datos, estados, KPIs — UNIVERSAL)
     --sem-success, --sem-danger, --sem-warning, --sem-info, --sem-neutral
     Significado FIJO. Solo varian en matiz para armonizar con el tema.
     Rojo siempre rojo. Verde siempre verde. El usuario siempre sabe que significa.
     Usar SIEMPRE para: badges de estado, KPIs, alertas, graficos, indicadores.
     NUNCA usar --color-primary para indicar exito/error/alerta.

   Variables inyectadas desde base.html via ConfigClinica + temas.py
