A selection change re-ran every CardFaceView on the board (180 bodies ≈ 85 ms on the 6×30 fixture, 515 ≈ 233 ms on a real 515-card board, debug): the face's body read store.selection in three places — isSelected, the drag replica's count, and the context menu's styleTarget — and Observation invalidates every reader of the property, past the equatable gate entirely. The band overlay stayed cheap, which is why the marquee tracked the cursor while the highlight lagged ~0.4 s behind. Now LaneView and TrashLaneView hoist one selection read per body and hand each face isSelected/selectedCount as compared parameters; StyleMenuItems takes its target as a deferred closure; TrashLaneRowView gains the same treatment plus the Equatable gate it never needed before. Select-one-card: 180 bodies → 1. A growing band costs the selection's own running size; the real board's crossing fell 233 → 112 ms — the remainder is lane bodies re-measuring their masonry, a separate lane-level finding recorded in RENDER-INSTRUMENTATION.md. Also: select() gains defaultsSoleMember — the marquee's explicit nils never avoided the sole-member default, so a one-card band acquired a selectionHead and could scroll the lane out from under its own drag. MarqueeRenderCostTests pins the shape: redundant samples cost zero bodies, a growing band pays per crossing, and selectionStillRepaints holds a ≤8 budget.
