/* ============================================================
   Calendario IFT v2.8 — estilos extra (complementan Tailwind)
   v2.8: sin cambios visuales. Solo bump de versión en el header.
         (Cambios funcionales: removida palabra "Equity" de UI visible y
          unificación de localStorage en una sola key — ver app.js.)
   v2.7: semana completa L-D (7 columnas).
     · Header de columna `.num` baja de 34px → 28px para respirar mejor en
       columnas más estrechas y no chocar con "SÁB" / "DOM".
     · Nueva variante `.session-card.w-tiny` para 3+ paralelas (cards ~70-80px
       de ancho): solo título recortado, padding mínimo, sin gloss superior.
     · `.w-narrow` se aplica desde 2 paralelas (antes era ≥3).
   v2.6: día festivo / bloqueado.
     · Form: toggle "Festivo", tint ámbar suave en .day-card.is-holiday,
       input opcional "Nombre del festivo".
     · Canvas: .holiday-overlay cubre la columna del día con tint plano
       y texto centrado vertical.
   v2.5: removido .sc-icon (emojis fuera). .sc-sub colapsa su gap.
