 * The public pages' ONE stylesheet (docs/26-landing.md §9, D598): the landing in four languages, «امتحان کنید»,
 * /download and the wallet's callback page. Served under /landing/ with `style-src 'self'`: every rule lives
 * here, never in a style="" attribute (D91). Both directions: spacing and placement are logical properties.
 * Motion (D596): only transform, opacity, stroke-dashoffset, clip-path and colours move; an element's own style
