   RARE SIGHT — product image zoom

   A single reusable viewer for every garment shot on the site: the
   collection grid and the homepage spotlight both open into this.
   Same overlay language as chat/promo — scrim + centred panel,
   opacity/visibility transition (never the `hidden` attribute + rAF,
   which silently breaks in a backgrounded tab).
