// User playtest #5 item 6 — "有两个吹风的风道确实做出来了，但是吹风机的贴图丢失了，反而在关底吹风机的贴图又出现了":
// act2autochess_m01 (战场#05(下半) 源石流发生装置) has 8 blowers (trap_013_blower, dir DOWN): the normal field's on the
// separator row 13 (cols 5 / 9, the partner's 13 / 17) blowing into rows 12–10, the boss field's on row 6 (cols 5 / 9 /
// 11 / 15) blowing into rows 5–3. The 3D board's normal / 联防 area stopped at row 12, so the normal field's blowers
// were never built (their airflow streaks — Pixi — still showed), while the boss field's were (the Final Assault view
// and — facing away, under the bench on the row-6 wall — the normal view).
// Now: the normal / 联防 areas take the separator row 13, and every active device standing on a built tile is drawn
// (render/board3d/layout.js stageDevices; the 2D board render/tiles.js _stageDevices follows the same rule — it used to
// drop an edge-wall device blowing away from the field, so the row-6 machines under the bench now show there too, as
// the user confirmed for the official normal rounds: "吹风机原版道中也该有", playtest #5 follow-up).
// Audit: for every stage and view the 3D board and the 2D board draw the same devices, and every active device is
// drawn exactly in the views whose area holds its tile.
