…n catalog - external service subscriptions needed end-to-end (Neon, Stripe, R2, TURN, hosting, Redis, domain/TLS + optional email/observability/CI) with required?, recommended tier, cost, and the exact env vars each maps to - in-app tier catalog (Free/Starter/Professional/Business/Enterprise) with limits, Stripe product/price + webhook setup, and a ready-to-run plans seed SQL - provisioning checklist + local dev shortcut
…etworking The compose/SFU media config had two latency-critical mismatches: the SFU code reads MEDIASOUP_ANNOUNCED_IP / MEDIASOUP_RTC_MIN_PORT / MEDIASOUP_RTC_MAX_PORT but the compose set ANNOUNCED_IP / RTC_MIN_PORT / RTC_MAX_PORT (silently ignored), and the published port window (10000-10100) did not match the worker range. Either would have forced TURN relay or broken direct WebRTC connectivity. - docker-compose SFU service: rename to MEDIASOUP_* names, set range 40000-49999, switch to host networking for the lowest-latency media path (no Docker NAT), and reach Redis via its host-published port. - Correct sfu/.env.example, .env.example, and DEPLOYMENT_GUIDE.md to the same names/range. - Update docs/MEDIA_INFRASTRUCTURE.md and SUBSCRIPTIONS_AND_TIERS.md to reflect the applied fix. https://claude.ai/code/session_01AMiTSxG8rB8FU8QgJ3Fnhs

Summary
Adds the self-hosted realtime media-infrastructure guide (Path A — Hetzner SFU + coturn) and fixes two latency-critical mismatches in the SFU/compose configuration.
Docs
docs/MEDIA_INFRASTRUCTURE.md(new) — complete guide for self-hosting the live screenshare + voice plane for true low-latency realtime: providers to sign up for, server specs (CCX dedicated vCPU), ports/firewall, latency budget, codec/transport tuning, sysctl + BBR, coturn specifics, DNS, multi-node scaling, and a pre-flight checklist withchrome://webrtc-internalsvalidation.SUBSCRIPTIONS_AND_TIERS.md— cross-links the media doc; corrected the SFU checklist line.Realtime SFU config fix
Two mismatches would have forced TURN relay (extra latency) or broken direct WebRTC connectivity:
MEDIASOUP_ANNOUNCED_IP/MEDIASOUP_RTC_MIN_PORT/MEDIASOUP_RTC_MAX_PORT, but the compose setANNOUNCED_IP/RTC_MIN_PORT/RTC_MAX_PORT(silently ignored → no announced IP).10000–10100vs worker default10000–59999.Applied:
