- Move import page, tabs, workflow state, and route tests into React-owned route slices
- Preserve shell gating, staging queries, album matching, singles matching, auto-import, and queue behavior
- Add migration plan snapshot so cleanup/refinement can build on a stable baseline
- move the stats route onto the React shell with Recharts-based visualizations
- remove the global Chart.js include and add a local stats seed script for easier testing
- keep parity coverage with route, API, and helper tests while preserving the legacy page layout
- add canonical /artist-detail/:source/:id TanStack route
- hand the legacy page off through the shell bridge
- remove artist-detail branching from generic shell helpers
- File-based routing with tanstack router
- Persist top-level navigation state in url, even for most legacy pages
- Striving for an intuitive and simple folder structure where
route-related code is colocated, but the amount of files is still
kept to a minimum
- Replace native fetch with `ky`
- Familiar api, but more polished
