/*
 * site.css — Skerply marketing surface.
 * Brand pack v1.1 — 8-iteration polish pass on the marketing shell.
 * Layered on top of brand/tokens.css and brand/fonts.css.
 *
 * Contract:
 *   - Every translate/scale lives inside an @media (prefers-reduced-motion:
 *     no-preference) guard or @keyframes block.
 *   - Every `animation:` referencing --duration-220/360/600 is inside the
 *     same guard.
 *   - Reduced-motion users see a 0–120 ms cross-fade or no motion at all
 *     (durations are clamped in tokens.css).
 *
 * Iteration map:
 *   1 — Container, grid system, baseline rhythm
 *   2 — Hero composition (text + product-card visual)
 *   3 — Typography scale, eyebrow labels, refined nav
 *   4 — Trust pill row with icons + dividers
 *   5 — Numbered phase cards with connector + reveal stagger
 *   6 — CTA band gradient, button gloss + arrow
 *   7 — Footer redesign (4-col + fine print)
 *   8 — Polish: sticky header, scroll cue, dark, print, perf, a11y
