Affiche de lancement de produit, montagne de gelée de raisin vert

Around any thematic object, generate a visual system with the feel of a festive commercial poster: the upper half keeps a large area of clean white space, with the theme name occupying the visual entry point in enormous high-contrast serif lettering (or a headline typeface of equal force), thin horizontals and thick verticals, generous letter spacing, creating a grand horizontal pressure. Below the headline, small spaced-out text, circular badges or seal-like short phrases create a light rhythm, letting information hover like ritual markings. The lower half translates the thematic object into a close-up monumental main form: immense in volume, its top sharp or swelling, its surface made of edible-looking semi-transparent gel, sugar glaze, amber crystal or any translucent material derivable from the theme, inner textures faintly showing through, with runs of highlight, moist reflections and soft edges on the outside; the main form rises from shallow water, a mirrored liquid surface or glowing mist, its base swallowed by diffuse white haze and reflections, while smaller forms of the same kind recede in the distance to create depth. Colors derive from the theme's semantics but follow bright, clean role relationships: the background is mostly high-brightness, low-saturation emptiness; the main form occupies the largest color field in warm mid-to-high brightness translucent layers or the theme's core color; the dark headline carries the structural weight; a few metallic or highly saturated accents go to badges, side vertical text and local symbols, keeping the whole clean, bright and festive without muddiness. A tiny thematic figure, symbol or ornament may perch high on the main form as a scale anchor and narrative spark; sparse vertical short phrases along the left and right edges stretch the reading path like traditional inscriptions. Avoid turning the image into an ordinary product display — the key is that the headline's modern luxurious letterforms, the moist material of the crystalline colossus, the ritual information layer in the white space, and the water-and-mist reflections together create the first-glance impact of an "edible mountain monument". —————— Core subject: an ice-clear green grape jelly mountain with a snowy peak + cool summer ornaments Use case: new product launch cover image Color contrast: cool mint green + icy silver white + yellow-green accents + bright translucency Key visual layout: diagonal disruptive composition + vertical inscription on the left + vertical 3:4
