   HIGH TICKET SALES INSTITUTE — shared stylesheet
   --------------------------------------------------------------------------
   This one file styles every page of the site. It implements the two-layer
   brand from the positioning document:

     · The INSTITUTE layer  — gravitas. Paper backgrounds, navy text, brass
       rules. Used on trust surfaces (Employers, credential talk, the footer).
       In HTML: <section class="theme-paper">

     · The PLATFORM layer   — performance energy. Dark navy fields, light
       text, motion. Used on marketing surfaces (heroes, pillars, CTAs).
       In HTML: <section class="theme-dark">

   Plain-English map of this file:
     1. Brand tokens (colors, spacing, type sizes)
     2. Self-hosted fonts (Spectral + IBM Plex Sans, from the brand kit)
     3. Base/reset rules
     4. Typography helpers (eyebrows, display headings, leads)
     5. Buttons
     6. Header + navigation (including the mobile menu)
     7. Section layouts and reusable blocks (pillars, journey, facts,
        seven-beat spine, dimension cards, FAQ, forms, CTA band)
     8. Footer
     9. Motion (scroll-reveal, hero waveform) + reduced-motion fallback
    10. Responsive adjustments
