/* ============================================================================
   HOUSE UX LAYER — template 42 "Nadya" (navy & gold exclusive-07)
   Natural continuous scroll + derived navigation, on top of the existing
   navy/gold aesthetic. Loaded LAST (after exclusive-07.css and refined.css).

   Geometry tokens — real chrome never drifts from these:
     --header-h        header height (enforced on .site-header)
     --header-offset   header + breathing room, used for cover cap,
                       scroll-padding-top and scroll-margin-top
     --dock-space      body padding reserved for the floating dock (<1024px)

   Contents
     1. tokens & base geometry
     2. sticky header (brand · desktop pills · burger · progress hairline)
     3. mobile slide-down sheet + backdrop
     4. floating icon dock (<1024px)
     5. gate (top-cover) interplay
     6. cover = exactly one screen (cap + decoration trim ladder)
     7. scenes & free pages
     8. empty-state (.is-empty — visual only, print restores)
     9. unified zoom lightbox (images + placeholder video)
    10. scrollbars styled to the palette
    11. click-to-open OFF switch  (html[data-media-lightbox="off"])
    12. print — chrome hidden, everything visually hidden restored
    13. reduced motion
