- Add aria-hidden="true" to all decorative inline SVGs (bookmark, view-mode, funnel, checkmark)
- Convert save-search popover to proper dialog: role="dialog", aria-modal, focus trap, Escape key, focus return to trigger
- Add aria-pressed on list/map/split view-mode toggle buttons
- Add aria-expanded + aria-controls on mobile filter toggle button
- Add role="status" + aria-label="Đang tải..." on Suspense fallback
