Cosmic Compact Objects Showdown: A Visual Deep Dive

Prompt Text

► CANVAS & TITLE  
• 4K landscape infographic, aspect-ratio 3:2, matte cosmic-black background (#000014) with faint 5 % white gridlines.  
• Header bar (top 8 %): “COSMIC COMPACT OBJECTS SHOWDOWN” in white wide techno font; subtitle ribbon in neon-cyan monospace: “Black Hole • Neutron Star • White Dwarf • Pulsar”  

► MAIN ILLUSTRATIONS  
• Four equal vertical panels—front-facing conceptual renders of each object, 500 px tall, photoreal-cinematic:  
  1. **Black Hole**: dark central void, glowing red-orange accretion disc, gravitational lensing ring  
  2. **Neutron Star**: rugby-ball shape, ultra-dense surface, glowing hotspots at magnetic poles, field lines drawn in teal  
  3. **White Dwarf**: small bright sphere, soft white glow, spectral absorption lines overlay  
  4. **Pulsar**: rotating neutron star with magenta twin radio beams, starfield trails  

(Each render has a 12 px neon outer-glow matching its accent color: BH = # FF6A00, NS = # 00FFC8, WD = # FFFFFF, Pulsar = # FF00C8)  

► SPEC MATRIX (centre 60 % height; nine rows, thin neon separators)
