PROMPT:
Cosmic nebula with swirling gas clouds and a parallax star field.
Palette: deep space, magenta/teal gas. Signature: layered animated radial gradients for gas,
parallax stars, slow zoom.

TITLE:
Nebula — "Carina Drift" (Deep Field Survey, Sector Carina-North)

DESIGN DESCRIPTION:
An immersive, full-bleed window into deep space. A very dark multi-stop radial wash forms the
void, over which six large, heavily-blurred, screen-blended radial gradients drift and breathe
in magenta, teal and violet, layered so their overlaps bloom into secondary hues. A slow
counter-rotating conic gradient threads a swirl of gas through the cloud, and a luminous
pulsing core anchors the composition where a newborn star would be. In front, a full-screen
canvas renders a dense parallax star field — hundreds of softly twinkling stars with coloured
tints (white, pale blue, gold, rose) and a few bright ones with radial glow — plus occasional
shooting stars that streak diagonally across. A serif display title "Carina / Drift" (the
"Drift" in glowing teal italic) and a glassy coordinate readout float over the scene, framed by
an inset vignette for depth. The whole gas layer performs a continuous slow zoom.

MAJOR VISUAL TECHNIQUES:
- Layered animated radial gradients (six gas clouds) with mix-blend-mode:screen and heavy
  blur, drifting on different long, alternating keyframe timings to read as living gas.
- A counter-rotating conic-gradient "swirl" thread and a pulsing radial-gradient core.
- A slow, continuous "zoom" via a 34s alternate scale+translate on the whole nebula layer.
- Canvas parallax star field: per-star depth, twinkle phase, colour tint, and a few glow
  stars; pointer-driven offset plus a slow auto-drift for depth.
- Randomly spawned shooting stars drawn as gradient streaks with a bright head, fading on a
  sine envelope.
- Deep-space base wash, inset vignette, and a glassy overlay with a serif display title.
- A live/pause toggle button that pauses the gas animations and dims the field.
- Full prefers-reduced-motion fallback: animations off, static starfield rendered once.

INTENDED INTERACTION MODEL:
Ambient and exploratory. The gas slowly zooms and swirls on its own; stars twinkle and drift
continuously. Moving the pointer (or finger) parallax-drifts the star field and gas at layered
depths, easing back to centre; a "Live field · streaming" button toggles the animation on/off
and dims the canvas. All motion is replaced by a single static field for reduced-motion users.
