Lake Como Photo and Gouache Diptych

Goal: Create a vertical travel-aesthetic diptych about {argument name="destination" default="Lake Como, Italy"}, combining a vivid scenic photograph on top with a soft gouache sketchbook collage on the bottom. Canvas: Portrait 3:4 composition, split horizontally into two equal panels. No border between panels. The upper half is realistic photography; the lower half is an off-white paper background with airy watercolor/gouache studies. Top panel: A bright Mediterranean lakeside villa scene in crisp summer daylight. Show turquoise lake water filling the left foreground, a small wooden floating dock near the lower right waterline, ornate stone terrace stairs and carved balustrade on the right, a twisted carved stone column near the right edge, and lush pink oleander blossoms overhanging from the upper right. Across the water, show elegant yellow and cream villas with terracotta roofs, tall dark cypress trees, manicured gardens, and hazy blue mountains under a deep blue sky with a few white clouds. Use saturated but healing colors, cinematic travel photography, sharp foreground details, sunlit stone texture, tranquil atmosphere. Bottom panel: A minimalist gouache-and-pencil sketchbook layout on warm cream paper, with loose brush texture, soft edges, muted pastel palette, and lots of negative space. Include exactly 8 separate collage elements: 1) a small lakeside villa vignette at upper left with a yellow building, cypress trees, shrubs, a stone wall, and a pale blue water patch; 2) a handwritten quote near the upper center reading {argument name="upper quote" default="The lake keeps things we forget to say."}; 3) a beige spiral stone column sketch at upper right; 4) a small pink flower sprig beside the column; 5) a large pink oleander branch with green leaves at lower left; 6) a pale blue lake-water brush puddle in the center with a tiny brown wooden dock; 7) a pale blue simplified mountain silhouette near the lower center; 8) a small villa-and-cypress vignette at lower right with a yellow villa, red roof, green ground, and two tall dark cypress trees. Additional handwritten text: Place a second small pencil-written quote near the lower middle-right reading {argument name="lower quote" default="Light, stone, and the sound of somewhere staying still."} with a faint pink underline. Keep the handwriting casual, delicate, and slightly uneven. Visual style: GPT-image-2 aesthetic, split-media travel poster, top half photorealistic and richly colored, bottom half light gouache illustration, Japanese design-zine sensibility, soothing palette of turquoise blue, cypress green, sunlit yellow, stone beige, and soft pink. The overall mood should feel light, slightly clumsy, handmade, poetic, and calming. Constraints: Keep the exact two-panel vertical composition and the exact count of 8 illustrated collage elements in the lower half. Avoid people, cars, logos, watermarks, heavy outlines, or extra text beyond the two quotes.
