### Full prompt
```text
Pure black-and-white binary walkable-area mask for a top-down video game collision map, 2D orthographic view. Solid pure black background with a single connected irregular white silhouette representing traversable ground in a [fantasy dungeon or island layout]. The central mass features a broad vertical corridor with jagged pixel-stepped edges and six distinct branching structures: a large oval platform on the upper left connected by a narrow neck, a smaller mushroom-shaped platform on the lower left reached via a winding path, a jagged crescent protrusion on the upper left edge, an upper-right irregular chamber containing three narrow vertical black cutouts, a large black hook-shaped obstacle encroaching from the right-center, and a rounded lower-right chamber partially partitioned by black negative space. Style constraints: strictly two colors (#FFFFFF pure white and #000000 pure black), no grayscale, no antialiasing, no shading, no lighting, no texture, no perspective, no text; crisp pixelated mask edges suitable for SDF or collision mesh extraction.
