cap.mjs: - Replace the custom SwapButton (bottom-right) with a real ui.TextButton anchored top-right. Matches the rest of the app's button styling and keeps the bottom edge of the screen clear for the hold-to-record gesture. Box hit-test for the touch handler now goes through swapBtn.btn.box.contains(e). video.mjs: - Back button now properly slates the recording AND resets the local playback / export / scrub state on its way out. Without this, the in-flight tapeProgress bar, scrub strip, and post button kept drawing over a fresh cap session after the user hit Back. disk.mjs: - Route camera:debug and camera:debug:frame messages from bios.mjs directly to console.log inside the worker. The actAlerts queue only carries string keys, so these typed payloads were getting dropped before reaching cap.mjs's act() handler — which is why no cam/init / cam/frame events were showing up in piece-runs. Now they flow through to MongoDB and we can see what iOS actually hands back.
