What this proves

Before this commit, the local Quick-Play adapter buildPlayTableAdapter.ts mapped AntiCWNext(human) to screen-left. The visual rotation P1(bottom) → P2(left) → P3(top) → P4(right) → back to P1 is a clockwise sweep viewed from above, which disagreed with both the real-world Bangla Turup 29 rule and the team's own 2026-05-17 anti-clockwise correction already locked in adaptServerSnapshotToPlayTableState.ts, SLOT_BY_OWNER, and TrickCardModel.position.

The fix swaps left/right in buildSeatPositionMap(): right = AntiCWNext(human), left = AntiCWPrev(human). Visual rotation is now bottom → right → top → left → bottom — true anti-clockwise viewed from above. Engine logic, scoring, deck, redeal paths, and bidding rules are all unchanged (500-hand bot smoke: 500/500 pass, 0 errors).
