- Player: match webplayer.online's proven mpegts.js live-sync config
(deep 30-90s buffer, 45s target latency, 1.1x catch-up). The upstream
delivers in bursts with multi-second gaps (measured up to ~6s); the
deep buffer rides over them so 4K HEVC plays smoothly.
- Hub: on subscriber buffer overflow, cleanly disconnect the client so
it reconnects and resyncs from a TS packet boundary instead of
dropping bytes mid-stream (which corrupted alignment / sync_byte).
- Enlarge per-client buffer (256 -> 2048 chunks).
- Refresh real1.m3u from upstream.
