/* app.css — Ant Design v5's published design tokens, applied by hand.
   No React and no build step: the panel is five screens, and a bundler would cost more than it returns.
   Values below are antd's own (primary #1677ff, 6px radius, 32px controls, its elevation ramp) so the panel
   sits beside a real antd app without looking like an imitation. */
