Previous v202604241543backlog image accidentally used a stale
publish/ directory at the TtsReader repo root (Dockerfile.deploy
says COPY publish/ but my ad-hoc publish wrote to artifacts/publish/).
Rebuilt with a clean copy from artifacts/publish/ to publish/ first.
Confirmed new image has appsettings.json Preview section + the
quick-swipe-gestures.js asset baked in.
