# Product Center Navigation Feature Plan

**Goal:** Improve product filter interactions and connect homepage/product cards to their target routes.

**Architecture:** Keep backend IDs as the shared routing contract. Product filter state remains in `useProductCenter`; presentational components emit typed events and own only dropdown visibility.

- [x] Add failing tests for grouped selected tags, dropdown closing, product detail URLs, and country query validation.
- [x] Close filter menus after selection and outside clicks; render selected tags under their owning groups.
- [x] Link product cards to Inkpod detail pages.
- [x] Link all homepage free-trial actions to Inkpod login.
- [x] Render all backend-configured countries in a balanced two-row grid; switch countries in place and link category cards to combined country/category filters.
- [x] Run the full website test suite, production build, and browser interaction verification.
