- Settings → Slicer: pick Bambu Studio, OrcaSlicer, PrusaSlicer, Cura, a
custom open-link template, or plain download (remembered per browser)
- Bambu Studio / OrcaSlicer launch via their URL schemes with a 10-minute
signed download link (/dl/<token>/<name>) that needs no session cookie
- PrusaSlicer and Cura fall back to a download (they can't open our links)
- 3MF projects report which app saved them; opening one in a different
slicer asks first
- "slicer" action on every file row and archive entry
- Drag model cards (file, or zip of all files) and file/entry rows out to
the desktop via Chromium's DownloadURL
