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. ATMOSPHERE: a flat-graphic register -- no photographic texture, no gradient sky -- in a warm muted retro palette (mustard, burnt orange, faded teal, olive), one consistent light source from the upper-left, like a printed vintage text-effect template rather than a photograph. The two-word phrase is mounted as a large flat-illustrated sign above the entrance of a retro diner, filling about 70% of the frame width across two stacked lines. Flat vector illustration -- a striped awning, a round wall clock beside the door, a glimpse of a checkered floor through the doorway -- all rendered as flat color shapes with no photographic texture. Warm faded-teal evening sky as a flat color block behind the building, one consistent light source from the upper-left. 16:9 horizontal.
