Create ONE finished retro editorial coffee illustration poster, full bleed. Never a collage, grid, magazine mockup or paper photographed on a surface.
SCENE: "【場面】"
PERSON: "【人物】"
COFFEE: "【コーヒー】"
HEADLINE INPUT: "【一行の文】"
NAME INPUT: "【店名】"
Resolve HEADLINE once: if empty or "おまかせ", choose one short Japanese sentence suitable for the scene; otherwise use the input verbatim. Print only HEADLINE and the optional NAME, each exactly once. If NAME is blank, omit it without leaving an empty label. No other letters, numbers, labels or logos, including laptop screens, books and cups.
The four scene choices change only the action and props, never the illustration style: 出勤前 = fictional adult at a home desk with bag and morning window; 勉強中 = fictional adult student with open books, notes and desk lamp; 午後の休憩 = fictional adult leaning back at an office desk with laptop and leafy plant; 週末のカフェ = fictional adult by a cafe window with tiled table and pastry.
Use expressive, slightly caricatured but anatomically coherent adults, appealing tired or relaxed expressions, purposeful hand gestures holding the selected plain unbranded drink. Person input changes appearance and clothing; blank uses a short-haired adult in a cream shirt. Coffee blank uses a hot black coffee in a plain ceramic mug. Scene blank uses 出勤前.
Original 1950s–1970s magazine cartoon illustration: confident dark brown ink contours, hand-painted opaque gouache shading, fine halftone and warm paper grain integrated into the artwork. Warm cream, brick red, mustard and muted teal, deep layered interiors, richly drawn folds, ceramics, stationery, wood grain, window reflections. Large illustrated person and cup dominate the middle/lower canvas; contextual furniture and meaningful props densely fill to all edges, without random filler. A bold red/teal header sign integrated into the scene carries very large cream Japanese display lettering with dark offset shadow. Keep headline entirely within 15–34% canvas height, optional small name within 72–80%; all required text clear at thumbnail size. Text may wrap naturally into two lines but remains one sentence. No important text in top 12% or bottom 15%.
Render Japanese syllables verbatim, preserving every final consonant. Original fictional person and original lettering; no borrowed slogans, existing brand cups, trademark packaging, recognizable characters, artist signature, watermark, health claims, prices or made-up offers. Output only this one polished image. IMPORTANT: top 15% contains illustrated ceiling/window scenery only, no letters. Bottom 20% contains illustrated tabletop objects only, no letters. Place the shop name on a small desk plaque directly beside the cup, not at the foot of the poster. Headline sign is compact, not oversized: it occupies only the band between 15% and 34% from the top.
