# PartyUI (P8/P11) —— 组队成员信息板（1:1 迁移 `assets/root/uiparty.py` 的
# `PartyMemberInfoBoard` + `PartyMemberInfoWindow`；布局照 `partymemberinfoboard.py` 的
# 每员 106×36 条：StateButton(角色图标) + NameSlot + Gauge(HP) + 附加图标行）。
#
#   var pu := preload("res://ui/party_ui.gd").new()
#   add_child(pu)
#   pu.setup(m2client, canvas_parent, dialogs)   # dialogs 可空
#
# 每员一条 strip：角色状态按钮（队长可点 → 分配角色 / 踢人）、名字(+★队长)、HP 条、
# 附加效果格（affects[7] 非零 → 小图标 + tooltip）。整条点击 → 选中该员 vid。
# 顶部：EXP 分配开关（均分 / 不均分 → party_set_distribute）+ 组队治疗（party_use_skill）。
# `party_changed` 刷新；`party_invite_ask(leader_pid)` → 确认框 → party_answer。
