/* ============================================================
   BLOG INSTANET — Tema "Cuaderno" (hoja cuadriculada + máquina)
   ============================================================
   El usuario pidió que TODO el blog (listado y artículos) tenga el
   formato de hoja de cuaderno cuadriculada con tipografía de
   máquina de escribir, en toda la página (no dentro de un marco).

   - Fondo: papel #fffef8 con cuadrícula azul suave (26px)
   - Tinta: #1e293b texto, #1e3a8a títulos, #2563eb acentos
   - Tipografía: "Courier New", Courier, monospace (máquina de
     escribir, fuente del sistema — sin peticiones extra)
   - El .blog-cuaderno embebido en 3 posts se neutraliza (sin borde,
     sin caja) porque el tema ya es la hoja completa

   REGLAS DE SCROLL (heredadas de la auditoría 2026-08-10):
   - Sin min-height:100vh, sin overflow-x:hidden, sin touch-action
   - Tarjetas SIEMPRE visibles (sin opacity:0 dependiente de animación)
