  Max's ability: freeze decay of all platforms for a timed global window,
  with proper cooldown (40s) and clear start/end behavior.
  - When active, engine.decayPaused = true so platform ages are frozen.
  - Active lasts this.duration seconds (18s), cooldown decreases each update(dt).
  - On end, decayPaused is cleared and visual glitch cleared explicitly.
  - Uses a cleanup to ensure glitch does not persist.
