I didn't set up Biome and can't tell you why it wasn't working, but people on the team couldn't get the VSCode extension to show lint errors in their editor (Cursor, primarily). I misspoke about there being a CI issue. It was more like disagreeing with their defaults, e.g. `useHookAtTopLevel` and `noUnusedVars` are off by default.

`useHookAtTopLevel` is especially confusing since other React hook rules are on, and `eslint-plugin-react-hooks` defaults its analogue to "error".

But yeah, no linting in the editor was kinda bonkers.
