+- Transcribe a file: drop an audio or video file onto the app (or browse from
+  the dashboard) to get a transcript from the local whisper.cpp engine, with
+  live progress and cancel. Results land in History marked with the source
+  file and export as TXT, SRT, or VTT. Fully local; the optional AI cleanup
+  step is off by default for files. Requires `ffmpeg` (new doctor check).
+- File transcriptions are excluded from the dictation metrics (sessions,
+  minutes saved).
