Does a unit heal back to full health during cleanup after taking damage from a spell (Super Mega Death Rocket) that doesn't kill it?

Ruling: Units do not heal during cleanup. Units heal after each combat and at the end of turn.

Nuances:

• Cleanup is not a reset of everything; it's a cleanup of game state where dead units are removed and the state of attack/defend effects and other passives is adjusted
• All units heal after each combat (not just units that participated in that combat)
• Units also heal at the end of turn
