Create a square bedroom-door plaque graphic, designed as a complete physical sign rather than a movie poster. Render the exact headline text "LEO" as the dominant element, spanning 82% width across the upper-middle. Custom bold rounded humanist sans-serif letters: completely sans-serif, soft rounded terminals and corners, uniform monoline stroke, zero thick-thin contrast, moderately condensed proportions, distinct forward italic slant. Each letter is a thick extruded 3D block: saturated comic red front faces, royal-blue beveled sidewalls and deep extrusion, narrow matte-black separation lines, subtle cloth-like microtexture, polished clearcoat highlights. Use clean child-friendly geometry with no licensed character emblem, no recognizable face, and no trademarked logo. Set the exact supporting text "HERO HQ" centered beneath LEO, smaller but bold, in the same custom rounded italic sans structure, bright yellow-gold #F4C214 with a fine darker-gold lower edge and soft sheen. Place the exact text "AUTHORIZED ENTRY" in tiny spaced uppercase along the bottom edge, warm off-white ink. Composition: a rounded-rectangle door plaque with a dark navy enamel field, thick red outer rim and slim blue inner border; three small brushed-metal mounting screws at the top left, top right, and bottom center. Behind the lettering, build an abstract midnight city rooftop silhouette and a deep-blue radial burst. Fine non-branded spider-web strands stretch only through the four corners, kept secondary and never crossing the headline. Add small red, blue, and gold light specks. Strong upper-left white key light across the red letter faces, cool blue rim light defining the extruded edges, warm amber glow near the lower skyline, controlled shadow under each letter. Crisp sign-product rendering, centered symmetrical layout, high legibility from a hallway, print-ready, ray-traced reflections, clean edges, no additional text.
