Required confirmations

• I searched existing issues and did not find the same reproduction.
• I have provided the sample, repository, private receipt, or complete no-file inline reproduction using the selected method.
• I understand that screenshots and renamed file extensions do not replace a real sample or runnable reproduction.
• Any public attachment is sanitized and safe to redistribute for regression testing.

[github-actions]

Please add a sample or minimal reproduction. For configuration-only bugs with no file involved, exact package versions, configuration, commands and actual/expected behavior can be included inline. For rendering bugs, attach a sanitized file or send it to admin@flyfish.dev and record the date and filename. Screenshots alone do not reproduce a file failure.

Thanks for the report. Please share a sanitized CAD file, the exact package/browser versions, and the font names or custom font configuration so we can reproduce this.
