Plan step 23, containment.md § Missing ("Cards: the dragged state").
`data-dragged` on `<x-card>` takes the top of M3's card elevation scale
— Level4 (8dp) elevated, Level3 (6dp) filled and outlined — under the
16% dragged state layer from tokens/state.css. The row's hover and press
rules now exclude a dragged card, so the card a pointer is holding stays
at its dragged level. The application owns the attribute: nothing in the
browser tells a card it is being carried.
