Focused-card selection on the board: j/k or arrows move it, Enter opens, e archives, # pins, x trashes the focused card (actions gated off the Trash view). The selection is a brand ring on the card; it scrolls into view and clamps as the list/view changes. A window keydown listener on BoardView, ignored while typing, on a button/link, or while the editor modal is open. Added the card keys to the ? cheat-sheet.
