Create a finished horizontal birthday party banner, 16:9, designed for a child’s superhero 8th birthday. Exact readable text, set exactly as written: small top eyebrow "SUPERHERO BIRTHDAY PARTY"; dominant two-line headline "MILES" then "TURNS 8!"; centered event line "SATURDAY · AUGUST 29 · 2 PM"; bottom detail line "HERO HQ · 18 PARKER STREET"; tiny footer "CAPE REQUIRED. POWERS OPTIONAL.". Build the headline as original comic-display lettering: broad hand-traced uppercase forms with subtly variable brush width and ink pooling at joins; thick black outer outline, a narrow clean white keyline just inside it, then uniform circular Ben-Day dots on a 45-degree offset grid. "MILES" has flat primary red dot fill with a hard-edged royal-blue 45-degree offset drop shadow; "TURNS 8!" has flat primary yellow dot fill with a hard-edged red offset shadow. No gradients in the letters. Give the number 8 an oversized, slightly tilted shape, like it has burst through the baseline, with black speed marks. Composition: headline fills the center 75% of the banner width, with clear hierarchy and generous breathing room. Behind it, an original masked child superhero silhouette in red, blue, and black cloth suit leaps diagonally across a stylized nighttime city rooftop; featureless mask, no recognizable character or logos. Deep navy rain-slick rooftops and simplified Manhattan-like towers run along the lower third, with warm window dots and yellow taxi-light reflections. A comic burst of red and blue halftone rays radiates behind the title. Thin web-like linework frames only the four corners; floating paper-confetti stars, lightning bolts, and tiny halftone dots add party energy. Strong upper-left white key light, cool blue rim light, warm gold glow from the skyline, crisp print-poster textures, sharp legible typography, clean safe margins, no extra text, no logos, no watermark.
