/*
 * Public pages. Light only, by the owner's call: the site is the calm, sunlit
 * side of the app. Colours are AppColors (lib/core/design/app_colors.dart)
 * verbatim; the rose appears only where type needs it (links, focus).
 * Playfair Display (w500) sets headings, Inter sets everything read or
 * tapped, as in AppTextStyles — both the app's own OFL files, subset to
 * Latin + Turkish and served from this origin.
 *
 * Images are the app's own owner-attested photography, real app screens and
 * the approved movement posters (site/assets/img). Motion is CSS only — the
 * CSP admits no script — and every animation stops under reduced motion.
 * Scroll-linked reveals only run where the browser supports view timelines;
 * elsewhere the content is simply there.
