“TOWN TRUNK OR TREAT”是一张社区后备箱万圣节活动海报，风格活泼醒目。橙、绿、紫三色粗体字带有滴落的黏液效果，位于一辆敞开后备箱的SUV上方，车里有南瓜灯和糖果大锅，下方彩色横条中列出活动信息。你可以替换城镇、日期、时间、地点和报名截止日期，制作属于自己活动的海报。

Create a complete, print-ready 3:4 portrait flyer for a family-friendly town trunk-or-treat volunteer call. Keep every text line and key illustration within a 6% safe margin. Render only the following exact copy, with spelling, punctuation, and capitalization preserved: Small eyebrow: “CAR DECORATORS WANTED” Largest headline: “TOWN TRUNK OR TREAT” Supporting call to action: “Decorate a Trunk!” Event date and time: “OCTOBER 29 · 5:30–7:30 PM” Location: “Town Hall Parking Lot” Participation detail: “Sign up your car by October 22” Volunteer details: “Setup at 5 PM · Bring 100 treats” Closing line: “Costumes welcome!” Set the headline in bold, plump, slightly wobbly rounded display capitals with wide open counters and a thick deep-purple outline; use candy-bright pumpkin orange, slime green, and purple fills, restrained cartoon highlights, and just a couple of small rounded green drips. Keep every letter silhouette crisp and readable at phone-thumbnail size. Set all supporting copy in a clean, heavy, rounded sans serif with strong contrast and generous spacing. Use distinct poster zones: eyebrow and event headline at the top, the call to action beneath, a large decorated car trunk illustration in the center, then the date, time, location, signup, setup, treats, and costume line in compact, clearly separated blocks below. Make the event name the dominant type tier. Build the hero scene as a decorated open car trunk filled with individually readable wrapped sweets, a smiling carved jack-o’-lantern, paper bats, and a small pumpkin garland; no people are needed. Add a softly glowing full moon, a few silhouetted bats, sparse spiderweb strands, and low drifting violet fog against a deep midnight-purple background. Use warm pumpkin-orange lantern light on the trunk and pumpkins, green and purple accents, and a tidy pale-cream information panel so the small details remain legible. Keep decorations away from the copy; no blood, gore, QR codes, barcodes, extra lettering, or logos. High-contrast illustrated poster rendering, clean edges, layered paper-cut details, soft localized glow, print-ready hierarchy.
