Capacity
Per deployment, shared by projects (1–32); a create waits in line for a slot up to the admission wait (30 s default), then capacity_exceeded
Concurrent browsers per account
By the owner account's lifetime paid credit (default ladder: 1 before any payment, 2 from $5, 3 from $50, 5 from $200, 10 from $1,000; GET /v1/pricing); a browser past it answers concurrency_exceeded when the deployment enforces billing. The pool above is the hard limit under it
