/* Landing hero — main-domain UI/UX redesign (Batch 5).

   Loaded by landing.php after public.css and before plan_card.css. Owns
   only the new .landing-hero* component; the legacy .hero* selectors in
   modules/offers/css/public.css remain untouched and will be removed by
   Batch 8 once the rollout is confirmed.

   Acceptance contract from plan §5/Batch 5:
     - LCP image ≤ 80 KB AVIF.
     - Hero reserves height before the image arrives → no CLS.
     - prefers-reduced-motion disables the scroll-cue bounce + button micro
       transforms.

   All sizing comes from logical properties so RTL inherits without an
   `[dir="rtl"]` override block. Token references stay aligned with
   theme_a/tokens.css (--space-*, --primary, --surface, --text*, --muted,
   --radius, --shadow, --primary-rgb).
