Billing Seats Panel

A review-and-confirm card for changing seats. The white top shows a DesignLayer logo tile, “DesignLayer Team”, and “$12 per seat / month”. The gray bottom lists seats, prorated today, tax, and the next invoice, with a small minus and plus stepper under the total. Changing the count adds a “+2 seats” note and updates every amount. A Visa •••• 4242 line and full-width Cancel and Update seats buttons finish the card. Swap the logo, product, price, date, and card, then drop it into billing settings or team management.
