/* CHANGE LOG
 * 1 | maintainer@emeraldcoastsystemsgroup.com | The kernel screen kit (docs/ux/screen-standard.md): every kernel screen paints with the portal theme tokens, raises its cards, tiles and dialogs as glass over the theme's accent glow, lines its forms up on one grid, and shows records as sortable tables that stack on a phone. Low-specificity (:where) rules, so a screen's own stylesheet still wins on anything it names.
