   FILE TOOLS — ui/ux v3
   Design principles:
   • Neutral foundation (stone/slate) so tools feel calm, not loud
   • One strong accent (violet-600) used sparingly
   • Cards feel physical — real shadow, real radius, real hover lift
   • Typography does the work — no decorative elements
   • Every interactive element is obviously clickable
