Transform the uploaded winter cabin landscape into midsummer. Preserve the exact cabin architecture, mountain silhouette, stream path, rocks, tree positions, camera angle and composition. Melt all snow naturally; replace bare branches with full green foliage; turn the frozen foreground into grass, wildflowers and flowing water. Change cold overcast light to warm late-afternoon sunshine and update every shadow and reflection consistently. Photorealistic seasonal transformation with no added buildings or changed terrain.
