  -Internal cross-directory imports are allowed, but discouraged, and no module should re-export a symbol across directories.
  +Internal cross-directory imports are allowed from non-index modules to index modules, for example:
  +
  +```ts
  +// in components/ComponentX/ComponentX.tsx
  +import { UtilityX } from '../../lib/UtilityX';
  +```
  +
  +Imports that bypass an index file are discouraged, but may sometimes be necessary, for example:
  +
  +```ts
  +// in components/ComponentX/ComponentX.tsx
  +import { helperFunc } from '../../lib/UtilityX/helper';
  +```
