Entropy source

Picking a source changes the story on the receipt, never the quality: anything below class A is mixed with the OS CSPRNG before it reaches you. This result actually came from Live Weather.

Re-render keeps this token. Generate replaces it. That is the whole idea.

The token is the seed, so this link recomputes the result rather than looking it up. No database, and it works for as long as v1 does.

This page and /api/v1/g/numbers.timestamp run the same code. There is no private endpoint.
