“NORTHBOUND PLATFORM 04 N E S W”是使用 FontVibe AI 创作的粉笔文字效果。深色石板上的奶油色粉笔手写字：手写体与衬线混排，配花饰和小涂鸦，粉笔边缘柔和带粉尘，暖调咖啡馆灯光。

Create a complete portrait train-station pavement wayfinding graphic, viewed from directly above. The surface is dark charcoal, rough gravel-aggregate cement with visible small stones and shallow pits; show subtle station-platform context at the edges, including a tactile paving strip and a cropped rail groove. Do not show a framed chalkboard or wooden frame. Preserve the Chalk visual language through the dark active ground, warm ivory marks, restrained dusty pastel accents, small hand-drawn divider marks, and soft warm overhead station lighting. The main hand-lettered text is exactly “NORTHBOUND”. Make it large and clearly legible, running diagonally from the upper-left NNW toward the lower-right SSE, rotated 45 degrees clockwise from the vertical north–south axis. Use bold upright hand-drawn lettering with organic pressure variation, tapered stroke ends, uneven calcium-sulfate chalk coverage, dark skip-gaps that follow the rough surface, layered opaque passes, fine diffuse chalk dust just beyond the edges, and a completely matte finish with no highlights. Chalk adheres to the cement aggregate rather than appearing printed or painted. Place a compact, clearly oriented four-point compass rose in the upper-right area, with “N” above, “E” right, “S” below, and “W” left. Use simple chalk lines and tiny dusty sage and warm mustard accents on the compass only. Beneath the main diagonal lettering, set “PLATFORM 04” in smaller, clean hand-chalked capitals. Keep generous clear ground around each text block; the compass labels must not overlap the headline. The composition should read first as NORTHBOUND, then PLATFORM 04, then the compass directions. Use only the quoted text strings; no extra lettering, signage, logos, or watermark. Warm amber light falls from above-left, revealing the cement relief without glare.
