/*
 * landing.css — InkLift static landing-page styles.
 *
 * Cascade contract: this file MUST NOT declare CSS custom properties
 * (no --foo: ... definitions). All var(--…) tokens referenced here are
 * defined in /landing/css/design-system.css, which is loaded first by
 * landing/index.html and is a vendored copy of the backend canonical
 * design system (kept in sync via scripts/sync_landing_css.sh).
 *
 * Strict audit gate: scripts/audit_design_system.sh --strict enforces
 * (a) no token_def in this file, (b) all token_ref tokens exist in
 * design-system.css, (c) any raw hex color is on the allowlist.
 *
 * Layer order (last rule wins):
 *   1. Self-hosted @font-face block (Playfair / Inter / JetBrains Mono /
 *      Caveat, latin + latin-ext, served from /fonts/ — replaces the
 *      Google Fonts CDN link to cut FCP by ~300-500 ms on mobile).
 *   2. Reset + body baselines
 *   3. Skip-link + nav
 *   4. Prototype-derived landing sections (hero/pipeline/demo/features/
 *      devices/roadmap/trust/faq/footer/reveal/responsive)
 *   5. SAL-152 waitlist form CSS (appended verbatim at bottom so the
 *      shipped two-step form keeps its dark-on-black styling).
