+A small native Android app (`com.p0dcasters.tv`) for playing podcast episodes from HTTPS RSS
+feeds that the viewer enters. It includes no podcast directory, show artwork or preloaded feeds.
+The feed is fetched only after the viewer chooses Load; audio is played from the publisher's
+HTTPS URL. No dependencies beyond the Android SDK.
 
-- **WebView** on p0dcasters.com. Remote play/pause, fast-forward 30 s and rewind 15 s drive the page's player (`pitMedia`). Results open in the app; `mailto:`/`intent:` links go to the system.
+- **Bundled reader UI** (`app/src/main/assets/reader.html`): a local page with no external scripts,
+  images or catalog requests. Native code downloads the user-selected RSS document and accepts
+  HTTPS audio enclosures only.
 - **Remote navigation** (`app/src/main/assets/tv.js`): Chromium's WebView scrolls on arrow
-  keys instead of moving between links, so every D-pad press runs `pitNav(dir)` in the page:
