[1.58.44] — 2026-05-20
fix(ux): UX-D-L — #/deep opened Saved-research brief now has an inline × close button. v1.58.36 audit: clicking a saved-research card on #/deep rendered the brief body inline (Copy / Download / Open in tab / Generate PDF buttons in the header) but the user had no way to close the brief without scrolling away or navigating. New × button in public/js/views/deep.js showResult() header — clears out.innerHTML, mirrors the modal-close pattern (api.js UI.modal × button), keyboard-reachable, aria-label + title from new deep.closeBrief i18n key × 8. 937 → 938 unit. (UX-D-L)
