Added

• Interactive pricing calculator — choose a plan, enter expected monthly usage, and see estimated subscription and overage costs in one place.
• A "Try the pricing calculator" link on the Pricing page.
• A pricing FAQ clarifying that failed API calls are never billed and don't count against your quota.

Fixed

• Overage estimates no longer get inflated by APIs that aren't available on your selected plan.

Notes

• Good self-serve tool if you're trying to estimate what your usage will cost before committing to a plan.
