rendered as rainbow text effect — COLOR (mandatory): each individual character must contain a complete ROYGBIV rainbow gradient top-to-bottom within itself — top=red, upper=orange, mid=yellow-green, lower=blue-indigo, bottom=violet. NOT one color per character. NOT a gradient across the whole text. Every character is its own complete rainbow. Full chroma Pride flag saturation — not pastel, not muted, not shifted to any single hue. Deep pure-black background. '2,000' as rainbow neon glass tube characters centered at 68% width in 16:9 — each character a continuous bent neon tube, ROYGBIV color distributed left-to-right. Borosilicate glass tube physics: bright zone at top edge, dark interior shadow, outer glass specular highlight. Realistic 1/r-squared electroluminescent glow falloff — tight at tube surface, fading to black at 16px. Additive color mixing where adjacent character glows overlap. The characters appear to actually glow in a dark space — Las Vegas neon bar sign energy.
