/* ============================================================
 * NextGen MIS — Document viewer
 * ------------------------------------------------------------
 * Per-row Inspect/Download actions + a full-screen modal that
 * pages through a record's documents with rotate/zoom controls.
 *
 * Used by the beneficiary + applicant detail pages via the
 * <x-doc-viewer> component. No backend route is required: the
 * existing `file.download.file` route serves files INLINE
 * (response()->file()), so the same URL feeds both the <img>
 * preview and the HTML5 `download` action.
