extends PanelContainer
## The selected normal unit: portrait, name, stage, role, HP, damage, tempo, range, armour,
## ability, upgrade with cost and stat change, return value, and the lane order with TOP,
## MID, BOTTOM and GROTTE (only allowed options active). Normal units carry no items, so this
## panel has no item slots. In combat or after Ready it only informs.
