/* ─── Recursos · biblioteca personal de Rodolfo Manzur ─────────────────────────
   Se carga después de global.css en portada (teaser) y en /recursos/ y su hija
   /recursos/brief-por-voz/. Todo vive bajo clases .rc-*: no toca la nav, el
   footer ni el resto del home.

   Reglas de la hoja:
   - Tipografía MaximaNouva self-hosted (var(--font-primary), tokens/fonts.css).
   - Paleta Brava: #0A0A0A, blanco, grises, #EF1E1C y #C01710. Sin degradados.
   - Rojo pequeño sobre blanco va en #C01710 (6.2:1); #EF1E1C sobre blanco solo
     en texto grande o en elementos no textuales.
   - El header es fijo: 106 px en escritorio (36 + 70) y 92 px en móvil
     (32 + 60). El primer contenido arranca por debajo y las anclas descuentan
     esa altura con scroll-margin-top.
   - Movimiento local por hover, foco o clic; el pulso personal cancelable vive en resources-motion.js.
     Con prefers-reduced-motion no hay transiciones ni desplazamientos. */
