/* Whitepage - Independent App Website
 *
 * Themed via CSS custom properties. The page injects a seeded :root override
 * (palette + type pairing + corner/shadow scale) so every whitepage generation
 * renders a different look from the SAME markup — see wt_seed()/wt_theme() in
 * wt_common.php. The defaults below are the original slate/sky scheme and are
 * used verbatim when no override is present, so the page never depends on it.
