- replace all outdated flex-full utility classes with modern flex-1 across Vue components
- standardize scrollbar hiding by using scrollbar-none utility instead of verbose vendor prefixes
- update order detail page layout and scroll container styling
- add scrollbar-none usage guidelines to AGENTS.md documentation
