Focus and announcements in depth#

trap() stacks, recaptures and sees into shadow roots, roving() covers grids, trees, typeahead, RTL and the combobox aria-activedescendant pattern. Screen readers hear the app: two permanent live regions with a lossless queue, a route announcer with focus reset, focus that moves to a neighbour instead of <body> when a row disappears, audible loading / error / saved states and dialogs that name themselves.
