Harbor District Terrain Tilesheet 4x4

Generated from: Pixel art tileset sprite sheet for a 2D side-scrolling platformer, exactly 16 tiles arranged in a strict 4 by 4 grid (4 columns, 4 rows), equal square cells filling the whole image edge to edge, no extra margin, no gridlines, no labels, no separators. Flat front-on orthographic view, no perspective, no drop shadows, crisp chunky pixel clusters, dark outlines, readable when each cell is scaled down to 20x20 pixels. Melancholic urban-decay film-noir palette for a foggy wet dock harbor district: floor #24343a, wall #182127, accent #3f6f7a. READ ROW-MAJOR FROM THE TOP-LEFT CELL, in this exact order: row 1: (0) floor_top - wet concrete dock slab with a lighter wet top edge; (1) floor_fill - repeating wet concrete with faint tileable puddle streaks, uniform; (2) platform_top - weathered dock plank top with a lighter upper rim; (3) platform_fill - dark plank underside with nail lines. row 2: (4) wall - corrugated metal container wall with vertical ribs and rust streaks; (5) ceiling - dark pier underside steel beam ceiling; (6) ledge - dock edge ledge with a teal water glow underneath; (7) crate - a wooden shipping crate with cross bracing. row 3: (8) pipe_h - rusted steel pipe running horizontally with flange joints; (9) pipe_v - rusted steel pipe running vertically with a valve; (10) sign - a teal fog-light sign box made only of abstract glowing rectangles and bar shapes; (11) vent - a rusted metal louver vent. row 4: (12) sky - flat gray-teal fog haze backdrop; (13) silhouette_a - distant harbor crane and freighter silhouettes, flat dark shapes; (14) silhouette_b - closer darker warehouse roof silhouettes; (15) void - flat near-black fill. Seamless tiling: cells 0 through 6 are repeated across the level, so their edges must match up seamlessly with no unique shadow, gradient or vignette. Absolutely NO letters, numbers, words or readable text characters anywhere - evoke signage with abstract glowing shapes only. Keep all colors inside the listed wet teal-gray family.
