The usage panel's answers: where the account's quota stands, what the background PM last decided, and a way to make it sweep right now.

## TLDR

- No reading is reported as no reading, never as an empty bar — an empty bar reads as "nothing used", the one thing this panel must never imply.
- A hand-fired sweep runs even with the automatic PM switched off: that preference is consent to spend quota unasked, and this click is asking. The call waits for the sweep and returns what it decided, project by project, so the card can say it without racing a poll — and it can be narrowed to only working the queue.
