水平の記念碑性：巨大なボリュームと公共プラットフォーム

Design a convention center, museum, or civic institution inspired by Forum Building. Organize massive horizontal forms, minimal facade openings, deep structural shadows, and expansive public platforms into architecture emphasizing civic presence. An enormous triangular slab hovering above an open public plaza on few supports, almost no openings in the elevation, deep shadow beneath the mass, textured blue-grey cladding, people tiny on the plaza, hard midday light, eye-level composition, 24mm tilt-shift lens, ultra photorealistic, 8K
