   UNICÓRDOBA · GLASSMORPHISM 2.0  —  Premium / Subtle / Accessible
   ───────────────────────────────────────────────────────────────────────────
   PAUTAS DE DISEÑO (design tokens)

   1. OPACIDAD (background alpha)
      · Navbar (reposo) ......... 0.55   · Navbar (scroll) ... 0.80
      · Card principal .......... 0.64   · Card elevada ...... 0.76
      · Inputs / chips .......... 0.55
      Más translúcido que la v1 (0.85) → menos "lechoso", más vidrio real.
      Legible porque el fondo bajo las tarjetas es casi blanco (blobs 8–12%).

   2. DESENFOQUE (jerarquía por importancia del elemento)
      · Overlay / navbar ........ 28px  (flota sobre el contenido)
      · Card .................... 18px  (nivel medio)
      · Inline (input/badge) .... 10px  (nivel bajo)
      Saturación: 135% en superficies, 150% en navbar (antes 180% — se
      reduce para evitar el look sobresaturado de 2021).

   3. BORDE REFLECTANTE
      · Grosor: 1px (hairline). Nunca más grueso.
      · Color claro: rgba(255,255,255,.70) + arista de luz direccional (::before)
      · Color oscuro: rgba(255,255,255,.10) + arista esmeralda/dorada tenue

   4. SOMBRAS (profundidad en capas, no una sola sombra difusa)
      Receta = contacto (1–2px) + ambiente medio + ambiente lejano + inset top.
      3 niveles: --elev-1 (reposo) · --elev-2 (navbar/hover) · --elev-3 (modal/activo)

   5. ACCESIBILIDAD: contraste de texto AA (≥4.5:1) sobre el vidrio,
      focus-visible siempre visible, color-scheme nativo, reduced-motion.
