## Prompt

```text
Create a pure black-and-white binary walkable-area mask for a top-down video game map. Use a square 1:1 canvas, about 768×768 pixels, with a solid black background and a single connected irregular white region representing traversable ground. The white shape should resemble a fantasy dungeon/island silhouette: a broad central vertical open area, jagged organic edges, narrow corridors and protruding rooms branching left and right. Include exactly 6 prominent side features around the central white mass: 1 large rounded oval platform on the upper left connected by a thin neck, 1 smaller mushroom-like platform on the lower left connected by a winding corridor, 1 jagged crescent-shaped protrusion at the upper left edge, 1 irregular upper-right chamber with three narrow black vertical cutouts inside it, 1 large black enclosed blob-like obstacle intruding from the right-center edge with a curled hook tip, and 1 round lower-right room-like protrusion partially separated by black negative space. Add several small triangular notches and pixel-stepped jagged edges, but keep the image strictly two colors only: pure white for walkable space and pure black for non-walkable space. No text, no grayscale, no antialiasing, no shadows, no perspective, no texture; make the edges slightly pixelated and mask-like as if intended for SDF or collision-map conversion.
```
