v0.15.5

Changed

• Live view, no connection: the message stays put while it retries (the retry
  countdown has its own line, the waits grow from 2.5 s to 30 s), and the tab
  strip, navigation, address bar and toolbars are grayed out and inert until it
  connects. The session chip stays usable.
• Live view, connecting: the mascot dances (it floats with reduced motion), a
  progress bar follows the steps (finding the tab, attaching, setting up the
  page, …), and the step with its time is on a line of its own.

Added

• Small, springy animations: the nav icon hops when its section opens and counts
  pop when they change; the mascot in the rail waves on hover and hops on a click;
  New's plus turns; session cards float in; empty states float; the favorite star
  pops in and deflates; tiles and the live view's buttons squish when pressed
  (reload turns its arrow). None with reduced motion.
• The mascot in the rail or header always opens the list of sessions (it used to
  reload the page, which reopened the last view).
• Firefox without the companion: a focus ring shows which field or button has
  focus after a click or Tab. A Firefox window in the background draws none, so
  the extension draws its own; it hides while that window itself has focus.
• Live view: Alt+L focuses the address bar (like Ctrl+L in a browser, which
  can go to the page).
