Parallax Layer 3 Mid Architecture - Underground City

Generated from: Wide ultra-panoramic 2D game parallax layer, mid depth layer only (layer 3 of 4). Subject: the ruined mid-ground architecture of a dead underground street - a broken brick and stone colonnade and streetfront running across the whole frame: cracked brick facades, a row of ruined stone columns, dark doorways and empty window openings, part of a collapsed wall, a small stone stair stub, brick arches with missing masonry, scattered rubble along the base. Readable but dark: you can see brick coursing, chipped stone edges and mortar lines, yet the whole thing stays in shadow. A handful of windows and one or two doorways glow with warm amber-orange light from inside, the only bright points, casting no light onto the white background. Style: crisp illustrated 2D game art, graphic shapes, subtle gradients, hand-painted flat background art for an action-platformer. PALETTE LOCK: cool grey-teal stone and brick (#5A6E70, #46585C, #2E3B3E), deep indigo and violet shadow in the recesses (#1B1430, #2A1E4A, #3B2A63), muted slate blue for anything further back (#37456B, #4A5A7A), and small warm amber-orange window and lamp glows (#FF8A3D, #FFB25E, #E86A22) as the ONLY saturated accents. Nothing else saturated: no greens, no pink, no cyan neon, no rainbow. This is the inside of a ruined underground city, NOT a night sky: no stars, no moon, no sky gradient, no clouds. COMPOSITION: horizontally continuous across the whole width with no hard vertical seam, no edge and no break in the middle - the colonnade and streetfront run evenly across the entire frame so it can span a wide level; keep the middle horizontal band low-detail, low-contrast and uncluttered (plain dark wall and open empty space, no busy masonry or rubble there) so gameplay reads through it; put the arch, window, doorway and rubble detail toward the top edge and the bottom edge. Artwork bleeds all the way to the left and right edges. No ground plane and no floor slab: nothing that acts as a solid ground surface across the layer. ARCHITECTURE AND DEBRIS ONLY: absolutely no characters, no people, no humanoid figures, no faces, no creatures, no animals, no birds, no rats, no robots, no corpses, no statues of people, no silhouettes of people, no vehicles, no text, no letters, no numbers, no signage, no graffiti, no watermark, no UI, no frame or border. TRANSPARENCY SETUP: render the art as an isolated floating layer over one completely flat, uniform, solid pure white background (#FFFFFF) that fills every empty area edge to edge - no gradient, no texture, no shading, no cast shadows on the background, nothing else in the background, so it can be cut out cleanly.
