Breakout
Released
Bounce, break, repeat. Clear the bricks, chase the high score, don't drop the ball.
UI/DamageFlash.razor
A Razor UI panel that renders a damage flash overlay when the referenced BreakoutGame reports damage. It conditionally emits a div with class "flash" while Game.IsValid() and Game.DamageActive are true, and uses BuildHash to invalidate/rebuild when DamageSeq or DamageActive change.
