Sync robustness + a resync escape hatch for viewers who drift from the room.

New
Resync (self-only). When your player drifts from the room clock you get a prominent, dismissible "You're N s ahead/behind — Resync me" pill over the video (plus a top-bar button and a button on your own row in Members). Resync snaps only you back to the room — it never moves anyone else. For own-tab (site) sources the pill also shows inside the streaming tab, even with the widget minimized/closed.
Who's where. Each viewer now shows their live playback position, with an "out of sync" chip when they've drifted — in the Members list and in the widget's new Activity tab.
Widget reorg. GIF search moved above its results; tabs grouped into Chat · GIF (interaction) and Subs · Activity (player); the Activity tab shows who's watching, their positions, and the room's event feed.
Fixed
Genuine play/pause on slow custom players (which resolve a click into playback asynchronously) were being dropped and never reached the room — the gesture window was widened to catch them.
A viewer could silently detach from the room clock (a site auto-resuming a paused video, or a dropped cross-tab message) with nothing to correct it. A reconcile heartbeat now re-asserts the room's position, and a site that auto-resumes a paused video is re-paused locally the instant it happens — so it reads as "paused" instead of a play-then-snap loop.
Web + server are already deployed. Update the extension for the in-tab features; older installs keep working (the sync protocol is additive).

First release under the mutsu name (formerly sixseven) — same extension + room app, rebranded. Existing installs update in place (the add-on id is unchanged).

✨ Watching on sites that block embedding (Netflix-style)
A clear "Watch in your own tab" path when a source won't embed, with a tidy loading cover instead of the browser's raw "refused to connect" page.
Your already-open tab is paired automatically — no extra "Open tab" click.
"Play this page for everyone" moves the whole room to a new title (respects control mode); other viewers' tabs follow.
🪟 In-tab widget
Cleaner header: the room name links back to the room tab, plus dedicated minimize (to a floating bubble) and close buttons.
The toolbar popup shows its controls instantly (no wait for the page scan).
🔔 Update awareness
The room page now nudges you when a newer mutsu extension is available.
🐛 Fixes
"Reopen tab" focuses the existing tab instead of spawning duplicates.
The in-tab widget is removed when the room switches to an embeddable source.
Faster, more reliable detection of sources that won't embed.

Smoother watching on sites that can't be embedded (Netflix-style)
- When a source won't load in the room, you get a clear "Watch in your own tab" action instead of a bare "refused to connect" page; a tidy "Loading…" cover explains the wait.
- If you already have that site open, your tab is paired automatically — no extra click.
- New: "Play this page for everyone" — browse to a different title and push it to the whole room (respects control mode); everyone's tab follows.

In-tab widget — cleaner header: room name links to the room tab, plus dedicated minimize (to a bubble) and close buttons; closing shows how to reopen it.

Popup — widget controls and status appear instantly; a "page with player" is now offered as a watch-in-your-own-tab source.

Fixes — "Reopen tab" focuses the existing tab instead of opening duplicates; the widget is removed when the room switches to an embeddable source.
