  // module-boundary bans. Different key, no interference.

  // eslint rather than assumed:
  //   - `import { streamText } from 'ai'`  → this rule

  //     carry the restricted name

  //     `@typescript-eslint/no-require-imports` (inherited from
  //     eslint-config-next/typescript) already forbids require() anywhere
  //   - `await import('ai')`               → the no-restricted-syntax block below

  // bypass has to be written down where a reviewer sees it.
