Build a billing FAQ with Tailwind CSS: the usual accordion of billing questions, plus a sticky card summarizing the visitor's current plan — name, price, renewal date, payment method last four — with a manage button. Pull the plan data from the session when available, show a sign-in prompt card instead when not, and keep the recap visually distinct from the questions.
