   Two-column fixed-sidebar layout

   Layers below (do not redeclare):
     tokens.css   → all CSS custom properties
     base.css     → reset, fonts, .section, @keyframes fadeUp
     components.css → .btn-primary, .btn-secondary, .hero-tag,
                      .section-label, .section-heading, .footer-*

   Tokens used throughout:
     Color      → --c-*, --bg, --surface-*, --border*, --text-*,
                  --accent*, --green, --green-faint
     Typography → --font-*, --fs-*, --lh-*, --ls-*, --h-*, --p-*
     Spacing    → --sp-* (4 px base unit)
     Radii      → --r-*
     Buttons    → --btn-* (sidebar CTA reuses these)
