- Use ?: 0 fallback on filemtime() to prevent E_WARNING when files are missing
- Escape security_information output with $e() to fix XSS vulnerability (show.php:91)
- Wrap product image metadata in __meta container, move storage path into <details>
- Add table--details CSS class and th { white-space: nowrap } rule
- Remove redundant sort, sort_dir, per_page filter dropdowns from users list
- Add 10 as a per-page option in users list
