Maps Browser Key

The key the Maps JavaScript API is loaded with, served at runtime.

NOT baked into the frontend bundle, for two reasons that both cost real money. A bundled key cannot be rotated without a deploy, so a leaked one stays leaked for as long as the release does; and it is identical across every environment, so a key scraped off the marketing site bills the same project as the product.

The value is USELESS to a scraper if it is restricted correctly: HTTP referrers we own, and the Maps JavaScript API alone. Configure that in the Cloud console — this endpoint cannot enforce it and does not pretend to.
