Animate this image with a seamless looping motion focused on light intensity rather than movement. The structure remains completely fixed and unchanged. The image slowly fades down in brightness, then fades back up, followed by a soft double blink (blink-blink) of light. The yellow and purple lines dim and re-illuminate together, with gentle glow variation, creating a sense of breathing and presence. The blink is subtle, warm, and restrained, never harsh or strobing. Black background stays solid and clean. No camera movement, no morphing, no new shapes. Perfectly loopable animation, calm, meditative, and alive.
