Drop-in transition styles for sortable lists, kanban columns, and reorderable cards. The enter/leave/move class convention pairs with any list-animation layer that toggles `motion-list-*` classes — siblings reflow smoothly while items fade-and-scale on enter/leave. Leaving items are taken out of layout flow (position: absolute) so the parent collapses immediately instead of waiting for the leave fade. All four timings and the settle curve are CSS variables (`--motion-list-curve`, `--motion-list-duration-{enter,leave,move}`, `--motion-list-leave-width`) so consumers tune per-context with one line. Consumed by `@uipkge/board` by default; usable standalone for any reorderable list. Tiny — one .css file, zero JS.
