- Share: a link that expired is never copied (the dialog and one-click Share pick a live one,
else make one), says it expired, and the copy-on-open claim clears on the next copy.
- A password-protected file link asks to open a file, not to watch a video.

the edit_spec docs name frame_w/frame_h; the join and rotated paths are tested.

- Tag chips count the followed channels (subscribed_count) and a toggled chip keeps the focus.
- Continue watching's See all sorts by last watched when in progress was already on.
