Build an in-app upgrade nudge with Tailwind CSS: a compact card showing the current usage against the plan limit as a progress bar with the exact numbers (820 of 1,000), what happens at the limit in one line, an upgrade button and a dismiss link. Change the bar to amber past 80% and red past 95%, and keep the card small enough to sit in a sidebar or dashboard corner.
