The Startup Gate That Makes a Python App Feel Native

I nearly shipped a build that looked healthy until the first launch hit a missing dependency. That kind of failure is useful because it tells you exactly where the app still feels like a script instead of software. The first thing I fixed was not the recording loop, not the UI, and not the transcription flow. I fixed startup. I think of that moment as a turnstile: the app either has the pieces it needs and moves forward, or it stops immediately and tells you what is missing.
