// Real-server browser E2E of user playtest #6 items 1 and 2 (from a friend): 凯瑟琳's device and 赫默's drone could not be
// placed by hand. A solo prep (test/e2e/fastServer.mjs hook SP_START_ROUND 2 + SP_START_CHESS: 古米, 凯瑟琳, 赫默 in the
// hand) is driven with real mouse drags: the three operators go onto the board through the direction wheel, their
// summon cards appear in the hand (赫默's 医疗探机 ×1, 凯瑟琳's 支援装置 ×2), the drone is dropped on a free tile and a
// device next to 古米 facing it — then the battle starts with both on the field: the device fights from the start and
// the placed drone deploys once at the battle start (PRTS 卫戍协议/帮助 §作战阶段; settled by the user after playtest #6 —
// shared/constants.js SKILL_SUMMON_START_DEPLOY), then comes back with each S2 (sim/content/tokens.js). Zero console
// errors.
