/*
 * Fieldbook marketing site: premium direction (mockup v1, 17 Oct 2026).
 * Colours come only from --fb-* tokens (design system v1.3): no literal colours or colour functions.
 * Lifted unchanged from HSOS-Branding's mockup v1.2 (https://claude.ai/artifact/FR49o2Wtj9jgKqSx2m7gsk),
 * apart from this comment; the site's own additions are in site-pages.css. Loaded only with Site:FullSite off.
 * Load after fonts.css and fieldbook-tokens.css. CSP-safe: no inline styles needed anywhere.
