Gaps in this history

Context caching prices from its 2024-06-18 launch until 2024-08-11 ($0.0875 / $0.175 per 1M cached tokens, capture 20240620163955) aren't in an event, because caching wasn't offered at the 2024-05-30 launch. No batch price: batch mode launched 2025-07-07, but the docs pricing page never listed a batch price for 1.5 Flash. Docs pricing captures from 2025-02-11 to 2025-09-26 show the 2024-08-12 card unchanged; the row was gone by 2025-10-05.
