@penpot/plugin-styles loaded Work Sans from fonts.bunny.net via a remote
@import in core/fonts.css, which every plugin built with the package
fetched at runtime. That broke air-gapped deployments, leaked user IPs
to a third party, and forced deployments to widen the CSP style-src
and font-src directives introduced in #11374.
Drop the remote import and use the system-ui stack instead of
'Work Sans' in the same package (both in core/fonts.css for code
blocks and in core/generic.css for the base typography, which relied
on the same webfont), so plugins no longer reach any external domain
and 'self' is enough for both CSP directives.
Verified by bundling the package entry point with esbuild using the
same options as tools/scripts/build-css.mjs: the produced styles.css
is balanced, contains system-ui, and contains no external import.
Closes#12023
