+- [x] 16.1 LiveKit-klient i frontend: installer `livekit-client`, koble til rom, vis deltakerliste. Deaktiver LiveKit sin auto-attach av `<audio>`-elementer — lyd rutes gjennom Web Audio API i stedet.
 - [ ] 16.2 Web Audio mixer-graf: opprett `AudioContext`, `MediaStreamSourceNode` per remote track → per-kanal `GainNode` → master `GainNode` → `destination`. `AnalyserNode` per kanal for VU-meter.
 - [ ] 16.3 Mixer-UI (MixerTrait-komponent): kanalstripe per deltaker med volumslider (0–150%), nød-mute-knapp (stor, rød), VU-meter (canvas/CSS), navnelabel. Master-fader og master-mute. Responsivt design (mobil: kompakt fader-modus).
 - [ ] 16.4 Delt mixer-kontroll via SpacetimeDB: `MixerChannel`-tabell + reducers (`set_gain`, `set_mute`, `toggle_effect`). Frontend abonnerer og oppdaterer Web Audio-graf ved endring fra andre deltakere. Visuell feedback (sliders beveger seg i sanntid). Tilgangskontroll: eier/admin kan sette deltaker til viewer-modus.
