Create a cinematic photorealistic widescreen promotional image for {argument name="headline text" default="GPT-IMAGE-2.5"}. Show one young woman adventurer in the foreground, waist-up, soaked by rain, with wet dark brown wavy hair, a muddy gray-brown open overshirt over a dark tank top, glowing skin highlights, and a joyful amazed smile as she looks upward toward the left. Place her slightly left of center, backlit by dramatic golden sunlight breaking through storm clouds. The environment is an epic fantasy-natural valley after a rainstorm: a vast lake and forested islands below, distant cliffs, mist, rain streaks, one large bright rainbow arcing across the upper right sky, and one prominent waterfall dropping from the right-side cliffs into the lake. Use high-end movie poster lighting, ultra-detailed textures, volumetric sun rays, lens flare, wet reflections, warm gold highlights against cool blue-gray storm clouds, shallow depth of field on the woman, and a 16:9 composition. Add the headline text in huge elegant uppercase sans-serif letters across the bottom third, cream-white with subtle gold glow, slight shadow, and a horizontal light flare crossing through the text. Keep the text exactly readable as {argument name="headline text" default="GPT-IMAGE-2.5"}, with no extra logos, captions, watermarks, or interface elements.
