The existing update_drop_highlights system tinted PileMarker sprites green for valid drops, but the marker is a card-sized rectangle that sits behind the stack. Once a tableau column had any cards on it the marker was occluded and the highlight effectively invisible — the handoff's "drops feel guess-y because there's no preview" point. A new update_drop_target_overlays system spawns an overlay above every legal target during drag: a soft DROP_TARGET_FILL rectangle sized to the pile's actual visible footprint (full fanned column for tableaux, card-sized for foundations and empty tableaux) plus four thin DROP_TARGET_OUTLINE edges forming a 3 px border. Z_DROP_OVERLAY = 50 sits above static cards (z ~1) but below the dragged stack (DRAG_Z = 500), so the overlay never occludes the card the player is holding. The valid-target enumeration mirrors update_drop_highlights exactly so the rules can't drift, and pile geometry mirrors input_plugin's pile_drop_rect. The original marker-tint system is untouched; it still does its job for empty-pile placeholders. The overlay layer is purely additive — running alongside, not replacing. Token values reuse the existing STATE_SUCCESS hue (#4ADE80) at 10% fill / 75% outline so the overlay green matches the rest of the success-signal palette (foundation completion, sync OK, etc.). Three headless tests pin the contract: overlay spawns for valid tableau drops, doesn't spawn for invalid destinations, and despawns the moment the drag ends.
