StarfieldBackground
fun StarfieldBackground(warp: Boolean, modifier: Modifier = Modifier, starColor: Color = Color(0xFFDFF6FF), streakColor: Color = Color(0xFF9CE9FF))
A perspective starfield.
Idle it is static (no animation, no redraws). While warp is true the stars accelerate toward the viewer and render as streaks — a Star-Trek-style warp jump — then decelerate back to a static field when warp returns to false.
