/*
 * Hand-written subset of the Tailwind classes used in src/views and public/js.
 * Replaces the Tailwind Play CDN, which needs modern JS and CSS variables.
 * Target floor: Samsung Tizen 3.0 TV browser (Chrome 47): no CSS variables, no grid,
 * no flex `gap`, no max()/min(). Grid and gap are enabled only under @supports;
 * older browsers get the flex + margin fallback below.
 * Adding a class to a view? Add its rule here too.
