A themed, token-only standalone surface — the canonical example every
new panel is copied from. It boots the shared theme pre-paint, honors
?theme= and ?embedded=, and styles entirely
through var() design tokens, so it renders correctly under
every family in both light and dark.
Representative content on an elevated surface with a tokened border.
Semantic status colors, each drawn from success / accent-secondary / error / accent tokens.
