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. '24H!' rendered as oversized, fully inflated candy-gloss balloon text, with the numeral pair, H, and exclamation mark carrying equal visual dominance and crisp readable silhouettes. Every individual character contains its own complete vertical ROYGBIV spectrum: saturated red along the top edge, orange through the upper body, yellow and green across the midsection, vivid blue and indigo below, finishing in deep violet at the bottom; never a gradient shared across the entire word. Thick transparent polyurethane balloon skin, rounded seams, subtle internal air volume, mirror-bright white specular streaks, and small reflected highlights from nearby lights. Surround the lettering with floating metallic balloons in hot pink, chrome gold, cyan, and violet, plus suspended paper confetti in every Pride-flag color. Background: an open-air Pride festival at late golden hour, bright turquoise sky fading to warm peach near the horizon, distant festival tents and string lights reduced to large circular bokeh. Sunlight from the upper edge creates sharp glossy reflections and translucent color bloom along the balloon contours. Clean high-saturation commercial 3D render, ray-traced reflections, crisp foreground details, bright celebratory palette, no dark areas, no extra words or symbols.
