Rework DrawCardDropShadow (Light/Marble): a Gaussian-sampled ring stack
matching a `0 0 4px rgb(50 53 58 / 34a)` box-shadow — offset-free, darker,
and tighter than the old faint 14px black halo. Clip to the shadow's own
bounding box (card ± reach) instead of the child window bounds so top/bottom
shadows are no longer chopped where a card sits flush with its container,
while staying on the card's own draw list (correct z-order in modals/popups).
