Prompt
Create a minimalist vertical poster on a pure black background featuring one large centered Chinese character, {argument name="character text" default="亮"}, rendered as futuristic neon tube typography. The glyph should be tall and narrow, occupying most of a 3:4 portrait canvas, built from thin rounded white glowing strokes with a faint cool blue halo. Use a custom geometric outline style rather than a standard font: rounded corners, open gaps between stroke segments, and elegant curved terminals. Add exactly 9 small decorative accent strokes: 2 short curved echo lines near the upper-left of the top vertical stroke, 1 slim vertical echo line on the right side of the upper section, 2 short horizontal bars inside the upper component, 2 diagonal slash marks to the right of the middle crossbar, and 2 diagonal slash marks near the lower-right/lower-left curved strokes. Keep the composition symmetrical and spacious, with no other text, no texture, no objects, no watermark, and strong contrast like a glowing white LED sign in darkness.
