+ * useDashboardSearch.js — the ONE free-text search the whole dashboard shares.
+ *
+ * ★ EXTRACTED FROM useDashboardShell (dashboard-kit landing 4a) BECAUSE EIGHT THINGS IMPORT IT.
+ * These three functions were exported from the shell, and every panel reached into the shell to get
+ * them: the table, the map panel, the charts rail, the facet rail, the research filters, the top bar,
+ * the profile and the config. That is not a shell concern; it is a module in its own right that
+ * happened to live inside one.
+ *
+ * It also unblocks the facet rail. Landing 4 was supposed to move the rail, and the rail imports
+ * these helpers — so moving the rail first would have meant a library component importing a plugin
+ * composable, which check:no-cross-plugin-imports rightly refuses. The dependency had to come first;
+ * SPEC-DASHBOARD-KIT section 8 did not notice that, and now says so.
+ *
+ * Nothing here is domain-specific: the accessors come from `config.facets`, `config.columns` and
+ * `config.searchKeys`, and the matching comes from the shared @map/components/search/fuzzy.js. A
+ * dashboard with different facets gets its own search for free.
+ *
+ * Bodies are verbatim from the shell — this is a move, not a rewrite.
