/* Profile Sentinel — landing (home.css) — IDEMIA re-skin 2026-07-10 · landing v2 2026-07-17.
   Scroll-snap "connected loop" pitch. Standalone stylesheet (this page does NOT
   link saip-design-system.css) → no global collisions; all classes local.
   Committed dark-cinematic keynote (deliberate single visual world).

   ACCENT GRAMMAR (codified):
     · filled url(#gr) artwork + .gt gradient pivots = SHIPPED capability;
     · 1.5px DASHED strokes/borders = PRODUCT VISION (#vision only — never a
       url(#gr) fill, never a CTA, never a link inside #vision);
     · problem screens (#cost #incidents #bottleneck) accent only via eyebrow
       + .gt; #shift onward may use win-tints.
   Future-state text keeps FULL contrast (>= #8479a0 on --ink/--ink2, prefer
   --muted); never opacity-dimmed text. */

/* stage / scroll */
/* NO scroll-snap on desktop (Sponsor 2026-07-22): with viewport-sized panels,
   CSS scroll-snap (even `proximity`) re-snaps a normal mouse-wheel tick (~120px)
   back to the panel start in Chromium — so the wheel appeared frozen and only
   the keyboard / dot-nav (which jump a whole panel via scrollIntoView) moved the
   page. Free native scroll matches what mobile already did (the max-width:820px
   block below dropped snap for the same finger-fight reason) and keeps the wheel
   working; the section pitch is still navigable via the dot-nav and Arrow/Page
   keys, which snap intentionally. scroll-behavior:smooth stays for those
   intentional jumps. */
