KanbanBoard lays columns of cards side by side. A card drags to a place in any column: it rides raised at the pointer, a slot opens where it would land, the other cards glide aside on motion::Flip, and the drop asks the owner through on_move(card, column, index); a drop in its own place asks nothing. Option with an arrow moves the focused card, whose focus the board keys by card so it follows it across columns. A press, Enter or Space opens it. Sprint Board is this board. IssueCard shows an issue's status, name, assignee, title, priority, labels and due day. TaskDetailPanel lays a task out in full: its title edits in place, its status, priority, assignee and due day change where they stand, and its notes and steps follow; each edit hands the whole task on, and a blank title is not taken. LabelManager tends a team's labels: a hue picked from a popover, a name edited in place, a delete, and a field that makes a new one; names stay unique in any case, and a refused name says why. The fill rule changes: min_w_full, taken up in T30d, resolves against a block's outer width in taffy 0.9, so a field in a padded card ran past its padding. A component that fills now takes no width on its root, which blocks and flex columns stretch; FormField and the new roots do. The chart's hue names move to theme::HUE_NAMES, which the event editor and the label manager share.
