/* Design system for the portal. Plain CSS, no build step, no remote assets.
   Page-specific composition lives in portal.css; everything reusable is here.

   Direction: "lobby directory". Warm paper neutrals, an ink inverse, one
   vermilion accent for action and focus, semantic colours only for status.
   Typography pairs a system serif for display with the system sans for
   reading and system mono for codes, counts and labels.

   Breakpoints (media queries cannot read custom properties):
     600px   two-column to three-column tiles
     769px   navigation expands, rows go horizontal (<= 768 is the mobile menu)
     1024px  side-by-side section heads, hero gets its board column        */
