/* RAMPA — sitio. Todo valor sale de tokens/*.css (RAMPA Design System).
   Reglas del sistema que este archivo respeta: radio 0, línea de 1px (2px abre capítulo),
   sin sombras / blur / glow, un campo por pieza (portada), ángulo 37.1°, hover por
   inversión o volt (nunca opacidad), press solo color, señal solo para desviación.

   Desviaciones deliberadas, por accesibilidad (decididas en la crítica del 2026-09-20):
   · La micrografía que porta significado sube a 11–12px; los 10px quedan para esquinas decorativas.
   · El foco es tinta sobre papel y volt (la señal da ~2.6:1 ahí); la señal se usa solo sobre tinta.
   · Parpadeo y malla corren tres ciclos y se detienen (WCAG 2.2.2). */
