# T03: Added partial_matches fallback UI to search results — shows muted suggestions when no exact AND match exists

**Added partial_matches fallback UI to search results — shows muted suggestions when no exact AND match exists**

## What Happened

Added partial_matches field to the frontend SearchResponse type. Updated SearchResults.tsx with partialMatches state, three-way rendering (exact results → partial match fallback → empty state), and a PartialMatchResults component that groups partial results by type with a muted header. Added CSS for banner and header styling with reduced opacity on partial result cards.

## Verification

TypeScript compilation clean (npx tsc --noEmit). Vite production build succeeds (52 modules). Browser verification with mocked API confirms partial match fallback UI renders correctly. Empty state still works when both arrays empty.
