rendered in kids birthday cartoon style with vibrant rainbow colors. Each letter in a different bright saturated color (red, orange, yellow, green, blue, purple cycling). Smooth shiny surfaces with highlight reflections. Large colorful cartoon balloons in multiple colors. Colorful star bursts, hearts, and confetti explosion. Maximum saturation, maximum fun energy. Children party illustration aesthetic. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the cartoon rainbow color, the shiny surfaces and the festive party scene. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as glossy cartoon letters each in a different bright saturated color, with balloons, confetti and starbursts. COLOR PRIORITY: keep the font's own colors if specified; otherwise cycle bright rainbow hues (red, orange, yellow, green, blue, purple). Render the exact text “ČETNÍK z MDST” as the dominant festive birthday graphic, preserving all Czech diacritics with crisp, fully legible marks. Give every character a different saturated rainbow fill cycling red, orange, yellow, green, cyan, blue, and purple, finished with smooth glossy cartoon enamel, rounded white highlight reflections, and a thick clean black contour. Build a child-friendly police celebration around the wording: a small blue-and-white cartoon police cap, a gold badge with a simple star emblem, a tiny toy patrol car with red-and-blue roof lights, and playful hand-drawn safety cones. Surround the text with inflated balloons in bright rainbow colors, curling ribbon streamers, dense confetti rectangles, paper stars, hearts, and radial comic burst shapes. Use a luminous sky-blue background with soft white cloud puffs, scattered polka dots, and pale yellow sunburst rays. Add a few glossy party candles and wrapped gift boxes with striped paper and oversized bows. Keep all props rounded, smooth, and non-threatening, with bold black cartoon outlines, maximum color saturation, clean vector-like edges, bright frontal studio illumination, and sharp readable text.
