# v1.0.285 #024 bundled Redmine CSS image 404 repair

- The copied Redmine 5.1.2 `application.css` referenced 109 images absent from previous #024 ZIPs, including `../images/arrow_down.png` (observed 404).
- This #024-only compatibility bundle supplies small generated fallback images at all referenced paths to eliminate missing asset requests. **These are not claimed to be exact official Redmine 5.1.2 image files.**
- The original bundled Redmine CSS is byte-identical. No CDN/network dependencies and no PHP.
- Installer copies each image; checks the served SHA256 of `arrow_down.png`, `arrow_up.png` and other selected assets. Node test checks all CSS URL paths and payload references.
- Real-user Windows/Edge HTTP test still required. Frozen #029/#048/#054 and SQLite assets are not modified.
