# T01: Added flex-wrap, max-width, and tighter mobile gaps to prevent horizontal overflow on ~412px viewports

**Added flex-wrap, max-width, and tighter mobile gaps to prevent horizontal overflow on ~412px viewports**

## What Happened

Applied five CSS changes to frontend/src/App.css: flex-wrap on .technique-header__tags, new .technique-header__creator-genres rule (existed in TSX with zero CSS), max-width + text-overflow on .version-switcher__select, tighter .app-main padding at 640px, and reduced .technique-header__meta gap at 640px. All changes prevent horizontal overflow on Galaxy S25 Ultra width viewports.

## Verification

npm run build passes (48 modules, 774ms). grep confirms flex-wrap: wrap and technique-header__creator-genres present in App.css.
