// ESLint config of the client: the Rules of Hooks, and nothing else.
//
// Formatting and the general lint baseline are Biome's job (`yarn lint`). ESLint is kept for the one
// check Biome cannot make: react-hooks/rules-of-hooks, so a hook-order violation breaks the build the
// same way a typecheck or test failure would. Wired up as `yarn lint:hooks` (see package.json) and
// called from .github/workflows/ci.yml; the editor's ESLint extension reads this file as well.
