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. Background: vibrant outdoor festival scene — deep gradient sky from warm amber-orange at horizon to rich cobalt blue at top, soft bokeh of colorful light orbs (pink, yellow, cyan, violet) floating in mid-air suggesting festival lights or confetti. Strong directional sunlight from upper-right creating sharp specular highlights on letter surfaces. Faint colorful confetti scatter below the letters. The overall scene feels like a summer Pride festival or birthday celebration — never a plain white or studio background.
