Thread orientation (portrait|landscape) from client through API, engine, and image gen. Portrait devices render 1024x1792 (9:16) full-bleed scenes; desktop/landscape keeps 1792x1024 (16:9). Adds cover-aware click→image coordinate mapping, session-locked orientation, a shared coerceOrientation helper, and a choices overflow cap in portrait.
