IMAGE MASTER PROMPT

Create an original award-quality Japanese A4 portrait community participation flyer, 3:4. DESIGN PURPOSE: move neighborhood residents from passive awareness to joining a river cleanup by showing collective action without guilt or disaster imagery. Exact headline: 「川を、次の朝へ。」 Exact subheading: 「みんなのリバークリーン」. Three-level hierarchy: first a wide aerial photograph of a clean river bend running diagonally from bottom-left to upper-right with small anonymous volunteers distributed rhythmically along one bank; second the date 「10.18 SUN 8:00」 placed large inside the river's open water as a calm focal point; third a compact participation band at the bottom with meeting point, belongings, rain policy and 「参加無料・申込不要」. One visual idea: the diagonal river becomes the reading path from purpose to date to action. Fresh deep green, pale blue, white, safety orange only for meeting point. Highly realistic landscape and people at safe distance, sophisticated civic editorial design, clear Japanese typography, strong distance readability, restrained details. No real municipality, river, organization, sponsor, logo, brand, celebrity, watermark, eco clichés, leaves as decoration, jagged brush edges, torn paper, grunge, arbitrary corner blocks, blurred faces, malformed people or unreadable filler.
