   Full Calendar page — Banshkhali Blood Bank
   -------------------------------------------------------------------------
   Every rule here is scoped under `.cal-` so this file can never override
   or redesign the Home Dashboard Calendar Summary Card (`.db-cal-*`, in
   app.css) or anything else in the app. Uses the same design tokens
   (colors, radii, shadows, easing) as the rest of the theme — see the
   `:root` block near the top of app.css. See assets/js/views/calendar.js.

/* Premium canvas — a soft, neutral gray/off-white that reads as its own
   surface rather than an extension of the Home Dashboard's warm-porcelain
   background. Bleeds edge-to-edge inside .app-main the same way .db-page
   does (see app.css), but — unlike .db-page — DOES set a real, solid
   background: this page is meant to visually separate itself from the
   Dashboard, not blend into whatever the Background Manager is showing
   behind it. Purely a visual change; no markup/behaviour is touched. */
