 * KlarFort website — unified with the app's design language (iOS canonical).
 * Mobile-first: 320px+ default, tablet >=600px, desktop >=880px.
 * Color tokens mirror shared-data/colors.json; radii/spacing mirror dimensions.json.
 * Typography mirrors the app: SF Pro with the ROUNDED design for titles/numbers/
 * eyebrows (web: ui-rounded resolves to SF Rounded on Apple devices; elsewhere it
 * falls back to the platform sans — exactly the app's own per-platform behavior).
 * CSP is 'self'-only: no font files, no external resources; all art is CSS/SVG.
