/**
 * Reusable ticket filter/search bar (UI rework #18): a free-text search input
 * plus the multi-select status/priority checkbox facets. Extracted from
 * {@link TicketsPanel} so both the main listing and the {@link TicketPicker}
 * popup share one implementation and stay in sync.
 *
 * Purely controlled/presentational — it holds no state and knows nothing about
 * the gateway; the owner (a view-model or {@link useTicketSearch}) drives every
 * value and toggle. Facet semantics (ticket #12): OR within a facet, AND across;
 * an empty set ⇒ that facet is unconstrained.
 *
 * The assignee filter stays with the main listing (it needs the project's agent
 * roster and is out of the picker's scope), so it is intentionally not here.
