/* ─── HERO CTA BUTTONS ───
   Restored: these were accidentally deleted in Task 6's scroll-jack CSS
   sweep (they lived in the same old .hero-standalone block as the
   scroll-jack-only rules, but are still needed by the Home hero and any
   other page's CTAs). Verified via `git show b0a528e:site/css/style.css`.
   NOTE: dropped the old opacity:0/translateY(20px) "entrance animation"
   state that used to be driven by JS tied to the removed scroll-jack hero —
   that JS no longer exists, so restoring it verbatim would leave every CTA
   button permanently invisible. The `.reveal` class on the parent section
   now handles the fade-in instead. Also updated `.hero-cta-secondary:hover`
   to use the current palette green (226,255,51) — the old rule still had
   the pre-b565aea cooler lime (60,230,25) hardcoded. */
