/* app.css — Bayris collaboration SPA components.
   Built entirely on bayes-theme.css design tokens (--bg-*, --text-*, --border,
   --btn-blue, --radius-*, --shadow-*, --font-*), so every one of the 26 theme
   variants (light/dark × 13 palettes) styles these components automatically.
   Visual language mirrors the SimServer social pages: dense, card-based, a blue
   primary + monospace "scale" chips, thin borders, soft hover lifts. */
