"The Monster Mash Lunch" 是一张复古风格的万圣节办公室聚餐邀请海报，风格俏皮。带紫色阴影的橙色粗体字下方，是一只戴派对帽跳舞的南瓜和一个南瓜图案的炖锅，背景为黑色，下方是奶油色文字。你可以替换活动名称、日期、时间、地点和报名联系人，制作自己聚会的邀请海报。

Create a complete, print-ready 3:4 Halloween office potluck invitation, designed for a 5×7-inch card and legible on a phone. Use a safe margin of at least 6% on every edge. The committed register is playful-spooky: no gore, blood, or horror imagery. Render ONLY these exact words, with no extra text: Headline, largest: “The Monster Mash Lunch” Small eyebrow: “OFFICE HALLOWEEN POTLUCK” Details, stacked and clearly readable: “THURSDAY, OCTOBER 29, 2026” / “12:30 PM · 4TH-FLOOR KITCHEN” / “BRING A SPOOKY DISH TO SHARE” / “COSTUMES OPTIONAL · PRIZE FOR THE BEST ONE” / “SIGN UP WITH DANA IN HR” Build a custom display letterform for the headline: broad, heavy, slightly irregular rounded slab capitals with compact proportions, chunky counters, and gently uneven baselines; cream-colored raised enamel lettering with pumpkin-orange inset strokes and a thin violet offset shadow. Keep every letter crisp and correctly spelled, with no drips obscuring the words. Set supporting text in sturdy, highly legible condensed sans-serif capitals, flat warm ivory, with generous tracking and clear line spacing. Use a three-territory invitation layout: small eyebrow at the top, headline dominating the upper third, a central illustration, and a compact but generously spaced details stack in the lower third. Center-align the composition. Keep all copy larger than 10 pt at print size and ensure headline and details remain readable at phone-thumbnail scale. Central subject: a smiling orange jack-o’-lantern in a tiny paper party hat doing a jaunty dance beside a covered potluck casserole dish, with a few small cut-paper bats and candy-corn shapes as restrained accents. Playful flat screen-print illustration with subtly raised enamel highlights; the subject supports the invitation rather than competing with its text. Deep charcoal-black paper background with fine uncoated stock grain, pumpkin orange, warm ivory, and a small amount of dusky violet. Crisp edges, controlled high-contrast studio lighting, subtle embossed depth, clean print registration, no border crowding, no additional lettering.
