Stations now render small and upscale in ffmpeg (wgtv 1280x720 lanczos, actv 960x540 neighbor) so type, QRs, and chrome read at YouTube size — Slidecop for the stream. AV sync: wallclock timestamps on both inputs, async audio resample, CFR out, 48kHz. unclutter hides the cursor. The watchdog gained a deploy-watch (RELOAD_URLS fingerprint → restart) so the panels always air the latest deploy, and per-station SIZE for its frame grabs. tv.whistlegraph.org QR grows to 148px. chat-bridge reads YouTube live chat via InnerTube get_live_chat — the official v3 liveChatMessages API returns bodyless 404s for these chats regardless of how the broadcast was created.
