Trial banner

How much of a trial is left, wherever a trial user looks: one row across the top of the app, or stacked in a sidebar. A ring empties as the days pass, the title counts down in days, then hours, then minutes, and one line says what has been used and what happens at the end. One action: add a card to keep the plan, or choose one. In the last two days it turns urgent through its color, not its size. With a card on file it stays calm, and when the trial ends it says the plan has started. Reads a Stripe subscription.
