/* ═══════════════════════════════════════════════════════════════
   AIMT Supporting Pages — shared primitives
   ---------------------------------------------------------------
   Reusable, supporting-page-only components: public footer, CTA
   variants, eyebrow, section container, form baseline, product-proof
   frame, reduced motion. The public nav lives in the separate
   assets/css/aimt-public-nav.css instead (one canonical header
   component, not bundled in here).

   Consumed by: index.html, courses.html, terms.html, privacy.html,
   refunds.html, verify.html, and the public #landingPage surface of
   headspa-mastery.html (scoped under #landingPage there — see that
   file's own note).

   Does NOT own page-unique composition (heroes, curriculum explorer,
   Fit Check, dashboard layout, etc.) — those stay page-local per
   00-MASTER-DESIGN-SALES-SYSTEM.md §40.

   Depends on tokens in assets/css/aimt-design-system.css — load that
   file first.
