 - **Last-resort guard:** a panic hook plus `catch_unwind` around command dispatch and import/export turns an escaped
   panic into an error dialog and keeps the document. It's a safety net, not a licence; keep `panic = "unwind"` on native.
 - **Prove it:** every crash fix lands with a small synthetic regression test that panicked before the fix.

 ## Non-negotiables
 - **Clean-room.** Never read/disassemble anything inside Adobe app bundles (names/listings only). Never copy Adobe icons, presets, profiles (DCP), lens profiles (LCP), camera matrices, fonts. Observation of the installed Lightroom is read-only (it syncs the user's personal library: never import/edit/rate/delete there). Never copy GPL/LGPL/AGPL code (darktable, RawTherapee, ART, LibRaw, rawspeed, rawloader, rawler, lensfun, dcraw-derived GPL code…).
