A portrait-oriented surreal architectural vision: an immense cathedral built from translucent ribs of light and deep blue stone, suspended in a boundless dusk. Its corridors do not obey geometry; they curve toward a distant, unreachable warm glow visible through countless open doorways. Staircases rise into empty air, archways lean toward one another without touching, and delicate golden threads stretch across the vast interior like silent invitations. At the center, a small human silhouette stands beneath a vaulted ceiling shaped like a slowly opening heart, while constellations drift through the walls. The structure feels older than mathematics, intimate yet cosmic, solemn and luminous, with longing expressed as the force holding every impossible beam in place. Cinematic volumetric light, subtle mist, intricate monumental detail, dark indigo, ivory, and amber palette, dreamlike realism, profound negative space, no words, no symbols, no borders, portrait composition, 2:3 aspect ratio, ultra-high resolution
