PowerShell encoding artifacts - if they bother you visually, replace them manually
Sonnet 4.6/Extended —

The garbled /* â"€â"€ ... */ comment decorators in the CSS are a PowerShell encoding artifact — they’re invisible in-browser and don’t affect the CSS parser. If they bother you visually in the editor, you can replace them manually with /* ── ... ──*/ in the VS Code editor directly. I’d recommend not using PowerShell for file manipulation on this project going forward since it mangles the multi-byte characters.
