/* ==========================================================================
   Hero V2.1 — carousel visual layer (2026-07-17 rebuild)

   Visual contract: pixel-derived from the LIVE production hero
   (measured 1920/1280: H=595, title y127, sub y207, cta-row y270,
   search y345 w600, tags y433 · 375: H=400, y15/95/144/207/291).
   All four styles share ONE fixed-height container and ONE centered
   vertical rhythm; slides crossfade as full-bleed background layers.
     A 形象   — image + title/sub + section CTA (== live hero look)
     B 產品   — image + title/sub + auto price + booking CTA
     C 產品   — B + dark glass panel behind text (busy artwork)
     D 廣告   — operator's full artwork, zero overlay, search hidden
   JS: hero-gallery.js ([data-hero-v2] carousel + search state).
   Source mirror: sass/design-system/_hero_v2.scss
