/* ============================================================================
   BUG #15 fix (Tier 4 audit, 2026-05-08): [hidden] HTML attribute defaults
   to display:none with very low specificity (0,0,0,1). Any class-level
   `display: grid|flex|block` overrides it, breaking JS `el.hidden = true`
   semantics. Affected containers across Phase 2-16:
     .dp-wishlist-empty / .dp-wishlist-login-hint  (display:grid)
     .dp-offline-banner / .dp-recent-browse        (display:flex)
     .dp-resume-cart-banner                         (display:flex, body. selector)
     .dp-orders-empty / .dp-shop-empty              (display:grid, store-phase-2-3.css)
   Symptom verified on /profile/wishlist (not logged in): both #wishlistEmpty
   AND #wishlistLoginHint visible simultaneously.
   Fix: explicit [hidden] override with !important to beat all class chains.

   v45g (2026-05-08): 隱藏 site-audio.js 自動注入的 right-bottom 音樂 FAB
   on 商城頁面 (含 /m/store + /store + /store/*).
   User feedback: 「商城右下角 為什麼會有一個音樂的按鈕?」

   pwa.js (auto-inject 在所有 user page) 會載 /site-audio.js → 後者
   document.body.appendChild 一個 .site-audio-fab (position:fixed bottom-right
   48×48 button). 商城頁面 topbar 本來就有音樂 toggle (.dp-top-icon--music
   on /m/store 或 .site-music-toggle on /store), 多一個 bottom-right FAB
   是冗餘 + 擋到 cart FAB / 結帳 button.

   策略: CSS-only hide via :has() detection of store-specific markers.
   不能單純用 body.galaxy.marine 因為 /index.html homepage 也是該 class
   (homepage 仍要保留 FAB 一致行為).

   涵蓋:
     - /m/store, /m/store/* (mobile)        → body.dp-body--store
     - /store (desktop hero)                 → body:has(.store-page)
     - /store/cart                           → body:has(.store-cart-page)
     - /store/checkout / /store/payment / /store/confirm
       (uses dp-checkout-page / dp-confirm-page)
     - /store/orders                         → body:has(.store-orders-shell)
     - /store/orders/:id (SSR)               → body:has(.store-order-detail-page)
     - /store/item/:id (SSR)                 → body:has(.store-detail-page)
