Image: a CORNER section of a defensive STONE curtain wall

Generated from: a CORNER section of a defensive STONE curtain wall: two straight runs of coursed grey masonry meeting at a right angle, so that BOTH visible bases are proper ground edges — one run receding to the lower-left and the other to the lower-right, forming a shallow V at the near corner. Crenellated parapet with square merlons along both runs, visible mortar joints, a slight batter so the base is thicker than the top. Stone only, no timber. CRITICAL: both wall runs must be roughly the same length so the silhouette is symmetrical about the near corner, and each run's bottom edge must be a single clean straight line meeting the ground. The slope of those two bottom edges must be exactly one-in-two: measured in pixels, a bottom edge that travels 400 pixels sideways may only drop 200 pixels downward — no more. Draw the camera slightly lower so the V is flatter and lazier than a normal video-game castle wall. Hand-painted 2D isometric real-time-strategy game sprite art: crisp readable forms, natural saturated colours, visible brush texture, strong form shading that reads the object's volume. 2:1 dimetric isometric projection seen from above at a 30 degree elevation, so each visible base edge of the structure runs along a ground axis and descends exactly 1 unit vertically for every 2 units horizontally — a shallow slope, not a steep one. The key light is a warm afternoon sun from the UPPER RIGHT, so right-facing walls and roof slopes are bright and warm, left-facing walls fall into cool blue-grey shadow, and upward-facing surfaces are brightest. A single structure, centred, entirely visible, with a clear margin on every side. The background is completely flat uniform pure chroma-key green (#00FF00) and has NOTHING on it: no ground plane, no grass, no baseplate, no cast shadow on the backdrop, no border, no text, no watermark, no signature, no second object.
