 * OBJECT design tokens for ObjectMGMT, read from the UI kit's themes.css
 * (https://themes.apps.object.pl/api/kit/themes.css, linked in App.razor
 * ahead of this file). The kit puts data-theme="light" or "dark" on <html>;
 * the --obj-* names below re-point to the kit tokens of that theme, so the
 * component styles carry no code per theme. Square corners everywhere, no
 * drop shadows: depth comes from 1px teal hairlines and backdrop blur.
 *
 * The app sits on the kit's sheet (--paper) rather than on the teal page.
 * Dark keeps the look the app had when it was dark only: near-black glass
 * cards (--bg-surface, --bg-panel) on the sheet and teal hairlines.
