/* The APP SHELL and its components -- shared by the three operations sites
   (Airport Operations, the fleet dashboard, the installation tool). Colour
   ONLY through tokens.css (tests/web/test_ui_design_system.py).

   One system, used the same way on every page:
     spacing   8 px grid: 4 / 8 / 16 / 24 / 32
     type      12 label caps · 13 table · 14 body · 16 card title ·
               20 page title · 28 KPI · 36 hero word; numbers tabular
     radius    8 controls · 12 cards · 999 pills
     icons     the sprite in icons.svg, 20 px in chrome, 28 px in tiles
   Safety colour rule (tokens.css): quiet/veto grey, ARMED cyan outline,
   EMITTING the one magenta, FAULT red, stale hatch + "?", green only for
   "link OK". Navy is the BRAND and only chrome. Every state is icon + word
   + colour, never colour alone. */
