Primary prompt (copy-paste ready, with replaceable modules) Summer launch poster main visual for a fruit-flavored sparkling water, vertical layout, clean and airy. A single hero product at center—a clear, dew-kissed bottle or slim aluminum can—beads of condensation glittering like morning frost, effervescent micro-bubbles rising through crystal water. A crown of water splash arcs in a gentle S-curve, elegant and weightless, cradling fresh cut {FLAVOR_FRUITS} whose translucent flesh glows under backlight. Color palette is refreshing and sunlit: cool mint, seafoam, pale aqua, and cloud-white, with a precise accent keyed to the flavor (from the fruit’s skin and juice tone). High-key studio lighting with soft backlight and a crisp rim light, clean specular highlights, no harsh shadows; faint mist in the air and caustic reflections pooling on a glossy white surface. Background drifts from near-white to a whisper of color—a smooth gradient with soft, watery bokeh and delicate ripple hints—leaving generous white space around the product. Composition is minimalist and balanced: strong vertical axis, rule-of-thirds placement for the splash apex, ample negative space at the top-right for headline and at the lower margin for logo and QR code (no actual text). The label area is blank and pristine, slightly glossy, ready for branding. Fine, sparkling fizz threads around the fruit; ice cubes are glass-clear with soft internal refractions. Regional accent layer: {REGIONAL_ACCENT} subtly integrated at low opacity so it feels like a breeze of place, never stealing focus from the product. Ultra-clean, modern, premium beverage advertising aesthetic.

Constraints and layout notes

• Poster ratio: 4:5 or A3 vertical, generous bleed and safe margins, grid-friendly whitespace.
• One hero product only, centered; camera at slight low angle for stature; straight horizon.
• Keep background minimal and uncluttered; prioritize legibility for future typography.

Optional modules to swap per brief

• {FLAVOR_FRUITS}: choose one set per variant, and match the accent color
  • Lemon zest curls + translucent lemon slices (accent: lemon yellow)
  • Grapefruit wedges + pink pomelo pearls (accent: grapefruit blush)
  • Blood orange discs + zest flecks (accent: deep sunset orange-red)
  • Strawberry halves + tiny seeds sparkling (accent: soft berry pink)
  • Mango cubes + golden threads (accent: mango gold)
  • Lychee peeled halves + clear syrupy sheen (accent: pearl rose)
  • Lime wheels + mint sprigs (accent: lime green)
• {REGIONAL_ACCENT}: keep subtle (5–15% opacity), softly abstract, placed along edges or background plane
  • Mediterranean coast: sun-washed ceramic tile motif in pale azure along the lower edge; a soft horizon line of sea and distant white facades; a sprig of rosemary shadow, gentle and diffuse.
  • Tokyo summer: faint yukata textile geometry in icy indigo; out-of-focus paper lantern bokeh dots like floating pearls; a whisper of shaved-ice hues melting into the gradient.
  • Tropical Southeast Asia: delicate banana-leaf shadow pattern; turquoise pool-tile grid receding in perspective; hints of dragon fruit seeds like starry specks.
  • Nordic fjord: silvery mist gradient; minimal geometric “snowmelt” linework; a cool midnight-sun rim glow feathered behind the product.
  • California coastal: soft palm frond shadow; sandy off-white base fading to ocean teal; distant boardwalk lines barely visible.
  • Provence: lavender field haze as a lavender-gray film near the horizon; limestone texture ghosted at 10% in the corner; a bee-wing glint suggestion, abstract and light.
  • Urban minimal: architectural concrete texture at 8–10% opacity; glass reflections suggesting a skylight; crisp shadow lines implying a gallery space.

Negative prompt (to keep the visual clean and premium) Text, captions, letters, watermarks, brand names, extra logos, people, hands, busy backgrounds, multiple bottles/cans, crooked horizon, warped can or bottle, distorted label, low resolution, muddy colors, oversaturation, harsh shadows, heavy grain, chromatic aberration, motion blur, clutter, plastic-looking fruit, messy splashes, foam scum, stains.

Notes for generation control (optional)

• Style: ultra-clean product photography, high dynamic range but gentle contrast, photoreal with subtle CGI polish.
• Detail emphasis: razor-sharp condensation droplets, crisp fruit texture, fine sparkle in micro-bubbles, smooth gradients without banding.
• Keep the regional accent extremely soft; it should feel like a scent of place rather than a pattern dump.
