/* ============================================================================
   Jaq Figueroa Interiors — "Grand Tour"
   Pattern: full-page scroll-scrubbed film (one continuous walk through one home).
   Forked from the CertiPro Pattern-3 engine; retinted to the Figueroa brand.
   Modes:
     scrub  → desktop/fine-pointer: 192-frame canvas scrubbed by whole-page scroll
     video  → mobile/coarse/low-mem/save-data: ambient looping <video> bg
     static → prefers-reduced-motion: single poster frame, no motion
   Legibility doctrine: text NEVER sits raw on the bright film. It rides an
   Inkwell-glass island with a brass hairline, or a local scrim. The film is
   decoration; the dark glass carries the contrast.
