Баннер с порталом в заколдованном лесу

A cinematic promotional landscape banner set in a dark enchanted forest at night. On the right, a massive ancient tree trunk features a hollow opening transformed into a glowing circular orange portal, revealing a misty blue mountain valley under stormy clouds within. Warm sparks, embers, and amber rim lighting surround the portal, reflecting off twisted roots, wet stones, moss, and the forest floor. The left side features deep negative space filled with silhouettes of tall trees and swirling blue volumetric mist. In the lower-left corner, exactly two visible typography elements are rendered in clean white sans-serif lettering: a large headline reading "[GPT Image 2]" and a smaller subtitle below reading "[Now on Blyth AI]". High-contrast teal and orange color palette, photorealistic fantasy environment, shallow depth of field, dramatic atmospheric lighting, no extra logos, no watermarks, no additional text.
