/* Seven Worlds public pages.
 *
 * The palette, the two typefaces and the engraved rules are the game's own, not
 * a website approximation of them: Cinzel and Sarabun are the exact files the
 * app bundles, subset here to Latin, and every colour is a token from
 * lib/core/theme/app_colors.dart. Somebody arriving from the Play listing
 * should recognise the surface.
 *
 * There is no inline style anywhere in these pages. Production Traefik serves
 * them under style-src 'self' with no 'unsafe-inline', and a page that needs an
 * exception to render is a page that stops rendering the day the header is
 * tightened.
