- Add tini (init: true in compose) to reap orphan Chromium processes - Reduce screenshot push frequency (active 0.12→0.20s, idle 0.35→1.00s, deep idle 1.00→5.00s, backoff 0.60→2.00s) - Add 5s timeout to screenshot in WebSocket push loop - close() now wraps context.close() in asyncio.wait_for(10s) with browser.close() fallback on timeout - Two-phase close logging (closing → closed / close_failed) - Auth-capture sessions evicted after 10min TTL - shutdown() with timeout protection and logging - close_ok correctly tracks success through browser fallback path
