Append a <style> block to <head> exactly once per id, whatever the call order or count, for chrome built
entirely with createElement (the palette, the panel frame). Rules should reference the host's :root design tokens
(var(--card), var(--hairline), ...) so the chrome follows the theme; those custom properties cascade from
wherever the tag lands.
