Function entropy 

pub fn entropy() -> u32

The app’s own draw, for the three-word name a new diagram is born under.

Through the host’s own randomness rather than RandomState, whose seed on wasm32-unknown-unknown is a constant: every tab in every browser would otherwise draw the same first name, and the collision retry would walk the same list behind it. A draw that cannot be made falls back to the clock, which is at least different per document.
