/* ============================================================
   Casey Technologies: global stylesheet
   Plain CSS, no build step.

   v3, 17 Oct 2026: ported from the approved redesign artifact (v6).
   A spec sheet for infrastructure work, light throughout. Pale
   blueprint bands carry the headlines and the stage-and-gate console;
   white and off-white sections carry the reading. Navy is for type and
   buttons, amber for markers. IBM Plex Sans for everything.
   One typeface, light surfaces only, no dark panels.
   Palette and type live only in :root.
