Under the hood
Publishing the design system now lets font files through even if permission rules would otherwise block them
What
When Claude Code saves 'the design system' to disk, it now checks whether a file is a font file. If it is, the file is allowed to be written even when the usual permission-rule filtering would otherwise have blocked it, and the write is tagged internally with the reason 'font file'.
Why
Font files are needed for a design system to render correctly, so blocking them on permission grounds could leave the design system broken. This exception avoids that failure mode for fonts specifically.
