- Conversation header: a bell on shared conversations — follow a guest's
conversation (owner) or mute one (anyone); the feeds refresh with it.
- Home: "waiting for feedback" skips forms addressed to someone else.
- Settings → Users: this month's spend against the budget on every card
header (all-time in the tooltip), a month summary across guests, and an
Impersonate button; "Back to admin" lands back on that card.
- An amber "Viewing as …" bar across the app while impersonating; the
guest Profile's sign-out reads "Back to admin" then.
