/* Miav marketing site — shared styles.
   Self-contained on purpose: no webfont, no CDN, no analytics. The page is one HTML
   request plus this file and two images, so it paints instantly on mobile data —
   which is the whole reason the apex is a static site and not the Flutter SPA.
   Light and dark both first-class, driven by prefers-color-scheme. */
