Breathing: deep amplitude so the pulse survives flicker fusion

At 20fps the previous narrow ramp (shades 17-33) flicker-fused into an apparent SOLID block on the VM. Amplitude now spans dark navy (17) to bright blue (45) in 12 steps — every frame is visibly different, cycle is 0.6s. Speed unchanged.
