/* ============================================================================

   Consumes theme.css (semantic tokens) and chrome.css (.container, .btn*) only.
   No :root block, no hex literals, no named CSS colours (darkgoldenrod-style)
   live here — see theme.css for the token contract, including the fixed-surface
   exception documented at theme.css:6-16.

   Three colour families are used, same convention as wwwroot/css/pages/home.css:
   - "Fixed dark" (--on-dark, --green-950 etc.): the hero and the principles
     section are always a saturated/dark brand surface regardless of the site
     theme toggle — branded moments, not theme-reactive content.
   - "Fixed brand-green" (--surface-brand / --on-brand): the closing CTA card,
     same family as Home's cta-grid/services/proof cards.
   - "Fixed light card" (raw --paper/--ink/--ink-soft/--line): the fan-selector
     demo widget and the showcase mockup-window frames are literal product
     screenshots in a light browser-chrome frame — they read the same in both
     modes, exactly like Home's .cta-form white card (documented in home.css).
   Everything else (jump nav, intro, showcase section backgrounds, slider
   controls, showcase copy) is the reactive semantic family (--bg, --surface,
   --fg, --fg-muted, --accent*, --border*) so the page participates in the
   site-wide light/dark toggle.
