+   Shared shadcn UI primitives (Button, Badge, Input, Select, Card, Table,
+   Tabs, Dialog, Switch, Checkbox, Tooltip, …) are built on the site's
+   semantic tokens (--color-background, --color-primary, --color-popover,
+   --color-border, --color-ring, --color-muted-foreground, …). On admin
+   pages we remap those tokens onto the admin palette so every embedded
+   component renders with the admin theme and guaranteed contrast, without
+   touching any component file.
+
+   Gated by `body:has([data-admin])` so the public site is completely
+   unaffected. This also covers Radix portals (Dialog/Select/Dropdown/
+   Popover/Tooltip) which mount under <body>. */
