// Real-server browser check of two player reports after the 0.1.0 release (placement legality, headless Chrome):
//   #3 "有水池的那张图干员可以错误的被部署到水里" — on 战场#08(下半) 涨潮控制 (act2autochess_m04, test/e2e/fastServer.mjs hook
//      SP_STAGE) the drag highlights of an operator never light the 深水区 (board (10–12, 6)) and a drop there is refused.
//   #9 "干员伺夜这样的战术家的战术点能被错误的被放到攻击范围之外" — while 伺夜's 狼群 card is dragged only the free legal
//      tiles of her attack range light up; a drop outside is refused, one inside opens the wheel; re-orienting her so the
//      pack falls outside her range sends it back to the hand.
// Real mouse drags (press, move, read the 'legal' highlight group of the view, release). Zero console errors.
//
//   SP_E2E=1 node --test test/ui/feedback1-placement.e2e.test.js
