[yusuftomilola]

Overview

Build a workspace search results page with a debounced live search input that filters workspaces by name and type. All work goes in frontend/sandbox/.

Acceptance Criteria

• Page at frontend/sandbox/workspaces/page.tsx
• Search input filters results as the user types (debounced 350ms)
• Each result renders as a workspace card: name, type, hourly rate, available seats, amenity chips
• URL query param ?q= is updated as the user types (shareable links)
• Empty state shown when no workspaces match the search term
• Loading skeleton shown while data is fetching
• "Clear search" × button appears when input is non-empty
• Uses mock data if no API is connected
