/* ============================================================
   frame.css — section background tones, decorative curves,
   shared section-heading blocks and card primitives.
   Curve strength: hero (strong, in image) > business (mid) > rest (weak)

   DEFERRED (2026-06-07, design-DNA pass): no new shared .c-* shelves yet.
   The home v5 consult-cta / external / trust bands still carry s-home-*
   naming and bespoke layout, so a generic CTA / card / section-heading
   component would be premature here. The disability page should build
   page-local sections using core.css tokens (--heading, --ink-strong,
   --muted, --surface-panel, --hairline, --shadow-panel, --fs-*). Promote
   a band to frame.css once the same pattern is confirmed on a 2nd page.
   The rules below are legacy/home primitives kept as-is for parity.
