/* QueueSim site layer (2026-09-27), docs/brand-style-guide.md.
   Loads AFTER each page's own <style>, so rules here win at equal specificity.
   Every page carries body.qs.

   Parts:  nav / footer (same markup on every page)
           type (text-wrap: headings balance, prose pretty)
           buttons  .btn.btn-primary (caramel, one per section) | .btn-outline | .qs-textlink
           bands    .qs-ground | .qs-ground-2 | .qs-warm (Deep Q closer)
           page     .qs-page-hero, .qs-wrap, .qs-cards
   No light bands anywhere: sections step between espresso tones, and the
   Deep Q closer (2.6:1 against espresso) is the only color band. */
