/* ============================================================================
   vendum.ai — home page redesign v2.1 (Atlas design language, own stack)
   Branch: vendum-dev/site-redesign-v2. Used by index.html ONLY.
   v2.1 after Nick's side-by-side review (2026-08-25 evening):
   - exact Atlas faces: Inter Display 700 headings, Source Serif 4 Italic tails
   - white page with the dark hero as an INSET ROUNDED PANEL (the "frame")
   - light navbar on the white field, black CTA
   - tile wall with visible running waves (their amplitude, not a faint breathe)
   - live workflow scene sits IN the hero (right slot), 6 mini-steps under it,
     autoplay ~2s/step
   Constraints: self-hosted assets only; opacity/transform animations only;
   no position:fixed anywhere; reduced-motion keeps the layer, stops motion.
   ========================================================================== */

/* Inter, UI symbols (F-FONTS): none of the
   four downloaded Inter weights contain ✓ ✕ ☰ -- see the fonts report
   for the full inventory and coverage table. U+2713 (✓) is
   subset from the already-licensed assets/fonts/InterDisplay-Bold.woff2
   (which does contain it); U+2630/U+2715 (☰ ✕) are absent from every local
   font, so subset from Noto Sans Symbols 2 (google/fonts, OFL) instead. Both
   declared under family 'Inter' so --body's existing stack picks them up
   with no HTML/JS change.
   Each declared at exactly ONE weight -- the pre-existing 'exact' bucket for
   its heaviest real consumer -- never as a font-weight RANGE and never at a
   brand-new weight value. Both were tried and measured (with the same CDP
   check qa.mjs uses) to corrupt Chromium's weight-bucket selection for the
   WHOLE 'Inter' family, not just the new unicode-range: a font-weight:400 700
   range face here made ordinary Cyrillic body text (bucket 400/500/600)
   fall back to the system font everywhere on the page; a lone new EXACT
   weight:700 face (with no 700 face for anything else) made unrelated
   weight:700 text with no glyph in that narrow unicode-range (plain digits
   in .pilot-point .on-mark) do the same, because Chromium picks ONE weight
   bucket per (family, requested-weight) for the whole element -- once an
   EXACT bucket exists it commits to it and does not retry a neighboring
   bucket per character. U+2713 (.approve-btn, weight 600) is declared at
   600, its own exact, pre-existing bucket. U+2715 (.on-mark, weight 700) is
   also declared at 600: no exact 700 bucket exists anywhere in this family,
   so 700 already nearest-matches to the existing 600 bucket (confirmed:
   .on-mark's own ✓ use at weight 700 -- and the unrelated digits in
   .pilot-point .on-mark, also weight 700 -- both resolve through bucket
   600 today); adding ✕ there needs no new bucket. U+2630 (.mobile-toggle,
   weight 400, no explicit override) is declared at 400: bucket 400 is ALSO
   pre-existing and exact for this family, so (per the same rule) it would
   NOT fall through to 600 on its own -- it needs its own 400 declaration.
   See FONTS-REPORT.md for the full isolation steps and CDP evidence. */
