Improve mobile layout for category chips and filter row #9
Description
On small screens the category chips row and column toggle can feel cramped. There's room to improve the mobile experience here.
Issues to address
- Category chips row and column toggle compete for horizontal space on narrow screens
- Active filters aren't always obvious on mobile
- Touch targets could be larger
Acceptance criteria
- Clean layout on screens 375px and up
- Column toggle accessible without scrolling
- No horizontal overflow
