/* PackTrack — guest-flow operations console.
   Enterprise-operations look (Trimble / Garmin / Cisco / Hexagon): clean, fast,
   restrained. Charcoal masthead + Great Wolf blue accent on an Apple-flavored
   token base. Light + dark schemes render together.

   RULES:
   - Never hardcode a color / spacing / radius outside this :root block — add or
     adjust a token and reference it everywhere.
   - Status TEXT (pills, badges) uses the WCAG-AA --label-* tokens; the vivid
     --color-* hues are for shapes (dots, accents, borders) only. A test in
     test/deployConfig.test.js guards the pill/badge text tokens — do not regress. */
