Do not use console.log, console.warn, or console.error directly unless in isolated files where importing loggers would significantly increase bundle size

207-212: LGTM! Verify the package export exists.

The addition of '@storybook/addon-docs/blocks' to the Vite optimization list looks correct and follows the existing pattern. The multi-line formatting also improves readability.

Please ensure that @storybook/addon-docs/blocks is a valid export path from the @storybook/addon-docs package to confirm this resolves the startup optimization issue mentioned in #32775.
