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.
