`source.locked` reads rows without writing them: no inline edits, New, delete or lane drags, and no property editing or visibility controls — while layouts, saved views, filter, sort, group, search and opening a record stay. `source.renderCard` swaps each gallery and board card's body for the page's own, inside the same clickable, draggable, selectable shell; `selection.getRowHref` makes the card a link for Cmd-click, middle-click and Copy link.
