0.2.6-dev: 魂灵之影 only on a board of its field (#557, PR #558 by IceCodeNew adapted) — shadowTile requires Battle.onFieldBoard: a teammate's half counts, a boss field's hand / 临时整备区 rows and a solo boss field's empty half do not, no summon when nothing fits (the PR cut the bench rows by number, which left an empty half legal); the PR's test plus a solo / pair case; DESIGN §3, §31.10, SIM; golden: unchanged
