/* ============================================================================
   Chasing Better — shared base stylesheet.

   Loaded by every athlete-facing page (not the one-off porto-sintra taper
   report, which has its own unrelated palette). Holds the CSS that was
   previously copy-pasted near-identically into every page's own <style>
   block — the drawer/backdrop chrome especially, which caused two real bugs
   this session when a new page forgot to include it.

   Deliberately does NOT include: .btn, .msg, .pill, .card h3, .metric's
   interactive states — these mean genuinely different things on different
   pages (a full-width gradient CTA on login.html vs. a bordered secondary
   button on core.html, for example), so unifying them under one rule would
   just force a visual change on whichever pages didn't get it that way
   originally. Those stay page-specific, defined after this file loads.

   .drawer / .hamburger / .cbc-topbar's SECOND, higher-specificity layer is
   injected at runtime by js/cbc-ui.js (search that file for "one hamburger
   definition shared by every page") — this file only supplies the base
   positioning/box-model CSS a page needs before that JS runs.
