------------------------------+-----------------------------
 Core bundles a pre-built copy of Gutenberg, pinned by commit SHA in the
 custom `gutenberg.sha` field of `package.json`. This ticket bumps that pin
 to `0e198c7ac7ca634e73ded9220ce048c0302174dd` and refreshes the
 regenerated build artifacts.

 The pin tracks the `wp/next` branch rather than Gutenberg `trunk`: trunk
 currently requires React 19 while core ships React 18, so a trunk-based
 bundle breaks the block editor. `0e198c7` is the current tip of `wp/next`,
 is React-18 compatible, and carries the HEIC client-side code.

 == Notes ==

  * The changed files under `src/wp-includes/{blocks,assets,build,images}`
 are regenerated Gutenberg build output, produced by `npm run
 gutenberg:download`.
  * `package.json`'s `gutenberg.sha` field is the only hand edit; `package-
 lock.json` is unaffected, because the SHA lives in a custom field rather
 than the npm dependency tree.

 == Patch ==

  * [https://github.com/WordPress/wordpress-develop/pull/12009 PR 12009] -
 `update/bundled-gutenberg-0e198c7`


 == Steps to reproduce / verify ==

  1. Apply the patch (or check out [https://github.com/WordPress/wordpress-
 develop/pull/12009 PR 12009]).
  2. Run `npm run build` and confirm the block editor loads without React
 initialization errors.
