/* ==========================================================================
   Texas Wing Group 3 Intranet — design system and application styles.

   Visual direction: an operational console rather than a corporate portal.
   A dark navy command rail against a light working canvas, hairline rules
   instead of drop shadows, squared 3px corners, uppercase tracked labels,
   tabular figures in every data table, and status carried by a left accent
   bar rather than decorative colour. Restrained Civil Air Patrol-inspired
   palette; no official CAP emblems or seals are reproduced.

   Everything is driven by custom properties in :root so the palette,
   spacing scale, type scale, radii and breakpoints can be retuned in one
   place.
