v. 0.5.8
Multi-Stream Play Together with Main Stream:

Expanded main stream integration on active Twitch and Kick channel pages to support 1, 2, or 3 pinned popups:
1 pinned popup + main stream: 2-stream 50/50 split.
2 pinned popups + main stream: 3-stream theater layout (main stream stage left, 2 stacked secondary popups right).
3 pinned popups + main stream: 4-stream 2x2 grid (main stream top-left).
The main stream tile automatically inherits the active volume and mute state of the host player upon entering tiled mode.
Background Audio Muting for 4 Pinned Streams:

When tiling 4 pinned streams (the maximum 4-tile layout limit), the host stream is excluded from the grid, and its background playback audio is automatically muted to prevent audio bleed-through.
Exiting tiled mode immediately restores the host video's prior volume and mute state.
Tile Close & Lifecycle Management:

Closing individual tiles while in tiled mode keeps background host audio muted as long as tiled mode remains active.
If the main stream tile is closed while other popups remain tiled, its latest volume state is saved and the background video remains muted until all tiled windows are exited.
Automatically restores host stream audio and returns to floating mode if the tiled window count drops below 2.
Dynamic Tooltips:

Action tooltips dynamically adapt to the current setup, displaying Dual+ with Main Stream (<channel>) (T), Play Together (<N> Streams) with Main Stream (<channel>) (T), or Play Together (Fill Screen) (T).

v0.5.7
- Video Playback Stability Fix: Resolved video stall issues and error recovery loops caused by event listener collisions in iframe player contexts.
- Removed Button Click Simulation: Eliminated programmatic mute button clicking on Twitch and Kick, preventing infinite MutationObserver click loops and background telemetry upload requests.
- Native Twitch Proxy Protocol: Uses the official Twitch Embed Player Proxy postMessage protocol for reliable volume and mute control without altering React DOM elements.
- Clean Host Video Muting in Dual+: When activating Dual+ from an active stream page, the underlying host video is cleanly muted rather than paused, preventing buffer underruns, live edge desync, and reconnect dropouts.
- One-Shot Content Warning Gate: Restricted content overlay dismissal to a single execution per preview instance to prevent mutation thrashing.

What's New in v0.5.5:
- Audio Playback & Unmute Fix: Resolved an issue where audio remained silent when unmuting streams in floating preview popups and Dual+ tiled mode.
- Twitch Player Audio Sync: Integrated Twitch's official embed player proxy protocol to ensure Twitch's internal player state synchronizes seamlessly with volume and mute controls.
- Kick Audio Handling: Added direct video element audio synchronization and native mute control tracking for Kick stream embeds.
- Enhanced Permissions Policy: Updated iframe media permissions to support unrestricted autoplay, encrypted-media (EME), and picture-in-picture decoding.
- Reliable Content Script Injection: Ensured extension player scripts reliably execute across all nested stream embed contexts.
- Dynamic Hostname Validation: Automatically resolves parent domain parameters to ensure embed compliance on both Twitch and Kick.
