/* site.css — all styling. Tokens only: no raw hex, no raw px outside tokens.css.
   Direction D (R7, 28 Sep 2026): "Apple × live" on the golden ratio. Spec in PROGRESS.md "## R7".
   Pieces (R8 checks every one):
   - .band (white), .band--alt (grey), .band--primary (blue, ONE per page), .band--dark (black, ONE per page)
   - centred section intros (h2 + first p) in a --container-narrow block on every band except .band--split
   - .band--split: 1.618fr / 1fr, photo in the minor column (:has() flips the columns when the photo comes first)
   - .callout: photo + --overlay-photo + one centred .glass panel; .hero--photo adds a CSS scroll-driven slow zoom
   - .site-header: sticky glass; static under 768px (no JS menu)
   - .button: pill; --accent always uses --color-on-accent (dark text on the orange)
   - .card / .review lift on hover; .tile and .person-card go white on a grey band
   - .fade-up: opacity 0 + translateY(--fade-rise) → visible over --motion-fade with --ease; reduced-motion → no transform
   - .underline-zigzag draw-in; .zoom-frame hover scale 1.06 */
