state-in-url

Define typed, module-scoped state and wrap useUrlState in a feature-scoped custom hook so unrelated React components share the same URL-synced state. Covers drawer/modal open-state, tab switching, multi-select toggles, reset/defaults semantics, and the object-identity-based sharing model. Load this skill when storing filters, tabs, drawers, selections, paginators, or any UI state that should survive reloads and be shareable by URL, and when a link to another route has to carry that state with it.
