“DINER SIGN”是使用 FontVibe AI 创作的长阴影文字效果。扁平45度长阴影文字效果，暖色调复古海报配色——就是复古设计模板常用的那种长阴影质感。

LONG SHADOW (mandatory, every letter): each letter casts a second, darker copy of its shape, dragged toward the lower-right at 45 degrees, 2.5-3x the letter height -- large, unmistakable, covering much of the background. NOT a plain letter with no shadow. NOT a small drop shadow. The shadow is one flat solid color with a crisp straight edge: no gradient, no blur, no glow, no bevel, no vanishing point -- flat, not a 3D block. COLOR: font's own color takes priority for the letter; the shadow uses a darker tone of it. No font color -> cream-white letter, deep brown-black shadow. BACKGROUND: a flat solid color (dusty mustard, burnt orange, faded teal, or olive), no texture, one light source from the upper-left -- like a printed vintage text-effect template, not a photo. The two-word phrase is set on two stacked lines, filling about 75% of the frame width, positioned slightly left of center with generous margin above and below suggesting a signboard layout. Flat solid faded-teal background, no other elements, one consistent light source from the upper-left. 16:9 horizontal.
