rendered as rainbow text effect — COLOR (mandatory): each individual letter 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 letter. NOT a gradient across the whole word. Every letter is its own complete rainbow. Full chroma Pride flag saturation — not pastel, not muted, not shifted to any single hue. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style always governs the color — every letter still carries its own complete top-to-bottom ROYGBIV rainbow gradient. FALLBACK MATERIAL: if the font carries no material of its own, render clean bold letters each filled with a full vertical ROYGBIV rainbow. COLOR PRIORITY: the rainbow gradient is mandatory and overrides any single font color — each individual letter is its own complete rainbow at full Pride-flag saturation. RAINBOW FIRE blazing as rainbow balloon letters — each individual letter a complete top-to-bottom ROYGBIV gradient, red crowning the top, cascading through orange, yellow, green, blue, indigo, down to violet at the base, at maximum Pride-flag chroma. Ultra-glossy spherical inflation on every letterform, brilliant specular hotspots catching dramatic upward firelight. Scene environment: a dark open-air night stage with roaring bonfires flanking both sides, casting dynamic amber and deep crimson rim light across the inflated letter surfaces. Towering plumes of real fire burst upward behind the text, their warm orange-gold light reflecting off the candy-gloss letter skins. Embers and sparks scatter like confetti, drifting upward in slow arcs. The ground below radiates heat shimmer. Colorful festival pyrotechnic sparks — red, gold, green, violet — explode in mid-air bokeh behind the letters. High-contrast chiaroscuro from the fire sources punches specular reflections across every glossy curve. Octane render, 8k, ray-traced reflections, dramatic rim lighting, ember particle scatter, deep black sky receding into infinite negative space above.
