Create a finished 3:4 vertical music-festival poster, printed 1960s Fillmore concert-poster composition. Full-bleed flat screenprint kaleidoscope: concentric radiating rainbow waves and op-art spiral rings expand from a giant central cosmic flower to every edge. The flower is a visible hero prop behind the title: 12 rounded petals with hard-edged alternating color bands, a cobalt-blue center containing a tiny cadmium-yellow starburst. Corner clusters of small groovy daisies, paisley curls, and four-point stars; no photorealism, no gradients, no shadows, no empty background. At top center, small curved uppercase text: “MUSIC & ARTS FESTIVAL”. Across the central 58% of the frame, set the dominant two-line headline exactly: “COSMIC” / “BLOOM”. Use chunky rounded custom poster lettering, thick even strokes, wide closed counters, compact line spacing. Every letter is filled with concentric contour bands echoing each letter outline ring after ring: hot magenta directly against acid green, electric orange directly against cobalt blue, cadmium yellow directly against violet. Equal-value adjacent bands, flat hard-edged ink edges, dense nested bands produce optical vibration and faint moiré shimmer. The title remains fully legible over the flower, with a narrow cobalt-blue keyline separating it from the background. Below title, centered uppercase: “OCTOBER 10–11, 2026”. Beneath it: “SUNSET MEADOWS · AUSTIN, TEXAS”. At the bottom, a small centered capsule badge reads: “TWO DAYS · THREE STAGES · OPEN AIR”. Supporting text is clean condensed cream lettering on cobalt-blue or violet flat shapes for immediate readability. Symmetrical layout, high-key even illumination like a backlit screenprinted poster, crisp ink registration, maximum saturation, hard edges, no muted colors, no gradient-soft rendering, no modern minimalism.
