Rules

balanced
- Run `biome check --write .` for combined linting + formatting — configure `biome.json` to enable TypeScript-specific lint rules.
- Use Biome's `organizeImports` to auto-sort imports — it replaces separate import-sorting plugins.
- Run `biome ci .` in CI (strict mode, no auto-fix) and `biome check --write .` locally for development auto-fixes.
- Enable recommended rules: `"linter": { "rules": { "recommended": true } }`.
- Use `biome ci` in CI pipelines — it exits non-zero on any violation without auto-fixing.
- Use `biome.json` overrides for file-specific rule configuration (e.g., relaxed rules for test files).
- Migrate from ESLint + Prettier with `biome migrate eslint` and `biome migrate prettier`.
