/* ============================================================================
   31 · "Sweet Simplicity" (insan, putih) — HOUSE UX LAYER
   Loaded LAST (after refined.css): converts the locked gate shell into the
   house pattern of natural continuous scroll while keeping the template's
   own aesthetic:

     · Desktop keeps the side-by-side design (§0): fixed hero pane left,
       scrolling column right — now starting below the house header.
     · Mobile: the fixed top-cover gate is gone. body.insan scrolls
       naturally; the top-cover is the first stacked scene, the
       "Buka Undangan" button a scroll cue.
     · House chrome on tokens: --header-h enforced on the header, cover cap
       and anchor offsets derived from it; scroll-spy header + dock; mobile
       slide-down sheet; zoom lightbox; print + no-JS fallbacks.

   Palette: the template's own monochrome — paper #FFFFFF, ink #1C1C1C.
   Nothing here changes the platform morph bindings (selectors, ids, the
   RSVP/guestbook forms, countdown, copy buttons, calendar export).
