Create a finished square 1:1 premium sparkling-water launch poster. Centered composition on a lavender-blue gradient studio backdrop, pale periwinkle at top fading to icy blue at bottom, with a glossy translucent acrylic floor. Render all artwork text accurately and exactly as quoted. Top eyebrow, small widely tracked humanist sans: “CRYSTAL COLD”. Main headline centered across the middle, two lines: “FROST” then “LINE”. Build it in a Calibri-like humanist sans: medium-bold weight, open apertures, broad rounded counters, low-to-medium stroke contrast, softly angled terminals, compact clean spacing. Cast the letters from optically transparent crystal glass, background visible through every glyph with refractive distortion. Show parallel glass-cut facets on the letter edges, pin-sharp white edge highlights, small bright internal caustic pools, subtle rainbow dispersion only on extreme edge angles. A physically distinct cap of wet crushed ice cubes and thin clear ice shards rests ONLY along the top contours of the headline, individual rounded cubes with trapped air bubbles, melting droplets, and tiny runnels sliding down the exterior glass faces. Do not turn letters opaque or frost them. Below headline, small clean sans: “SPARKLING WATER”. Beneath that: “0°C • SERVE OVER ICE”. Place a small circular clear-glass seal at lower right reading “EST. 2026”. Hero subject: a tall clear highball of carbonated water on the lower third, packed with transparent ice cubes and fine rising bubbles; its rim catches a thin white highlight. The glass sits behind the lower edge of the title without obscuring text. Strong diffused backlight from upper left, crisp narrow specular rim light from upper right. Project bright soft-edged caustic patterns and watery refraction across the floor beneath the glass letters and tumbler. Sparse floating condensation beads, no dark background, no opaque lettering, no extra text, no logos, no people. Clean high-resolution product-photography render, controlled negative space.
