## Summary - Replace generic Rails 404, 422, and 500 error pages with custom-designed pages - Each page features a prominent gradient error code, clean typography, and a "Back to home" CTA - Full dark mode support via `prefers-color-scheme` media query - Mobile responsive design - No external dependencies (self-contained static HTML, works even when Rails is down) - No logo/branding to ensure compatibility with custom-branded self-hosted instances --- ## Before (default Rails 404) <img width="2400" height="1998" alt="old-404" src="https://github.com/user-attachments/assets/c5f044c4-aab6-40e9-aa11-6096ed9d2b42" /> --- ## After ### Light mode | 404 | 422 | 500 | |-----|-----|-----| | <img width="600" alt="new-404-light" src="https://github.com/user-attachments/assets/1826c812-0eb9-4219-bdd2-026c54b53123" /> | <img width="600" alt="new-422-light" src="https://github.com/user-attachments/assets/d72ffdbf-b61e-4f53-a16b-4ee81103124f" /> | <img width="600" alt="new-500-light" src="https://github.com/user-attachments/assets/81bbdb24-bfe7-43a1-b584-f37f71e3bded" /> | --- ### Dark mode | 404 | 422 | 500 | |-----|-----|-----| | <img width="600" alt="new-404-dark" src="https://github.com/user-attachments/assets/bd323915-bfb9-48c1-885d-96ff263b4ae0" /> | <img width="600" alt="new-422-dark" src="https://github.com/user-attachments/assets/dcb08eca-aee5-4e36-9690-f44da13e8d88" /> | <img width="600" alt="new-500-dark" src="https://github.com/user-attachments/assets/538c3c2c-b9dc-406c-9932-ff8897b64790" /> | --- ## Test plan Easier way to verify: - [ ] Visit `/404.html` directly to verify the 404 page - [ ] Visit `/422.html` directly to verify the 422 page - [ ] Visit `/500.html` directly to verify the 500 page Full verification: - [ ] Visit a non-existent route in production mode to verify the 404 page - [ ] Trigger a 422 error (e.g., invalid CSRF token) to verify the 422 page - [ ] Trigger a 500 error to verify the 500 page - [ ] Toggle system dark mode and verify all pages render correctly - [ ] Test on mobile viewport widths
