0.2.6: the device slabs stay drawn on an official scene (GitHub #569) — 射击台, 特制水上平台 and 封印的地面 lived only in the procedural board's bucket that a scene replaces, so 战场#03's raised tiles by the blue gate were flat and 战场#05(上半)'s water platforms read as open water; buildBoard repeats them into buckets.raised / raisedDecal with sides reaching under the scene's ground and setStage draws just those on a scene (the 'h' high ground is the scenes' own and is not repeated); DESIGN §31.11, client §15; golden: unchanged
