Aurora Borealis

Animate [TEXT] as part of a northern-lights night sky. Wide, folded aurora curtains drift slowly across a deep navy sky full of faint twinkling stars: each curtain has a crisp bright-green lower hem, fine vertical rays, and fades upward into violet and magenta. Place [TEXT] large in the sky in a bold wide sans serif, its letters filled with the same streaked green-to-violet light and wrapped in a soft glow; let it brighten as a curtain passes through it, breathe gently, then dim as the curtain moves on. Below, black mountain and pine silhouettes sit on the horizon above a still lake that mirrors everything, broken by slow horizontal ripples. Calm, slow, seamless loop.
