プロンプト

Clean, professional event announcement banner with full-bleed <<BACKGROUND>>, all foreground elements overlaid on top.

Top band (~10% height, on the white background area):
- Top-left corner: <<LOGO_IMAGE>>, a small solid bright green <<BRAND_PRIMARY_HEX>> ginkgo leaf shape.
- To the right of the logo, <<BRAND_NAME>> in mid-weight dark-gray #585858 sans-serif.

Middle area (~65% height):
- Left side: <<SUPPORTING_IMAGE_1>>, a rectangular photo of participants, occupying ~45% of the banner width, placed on the white background.
- Right side, partially overlapping the plexus network graphic from the background: A large, flat, solid mustard-yellow #f0c300 circle.
- Inside the yellow circle, the three-line <<HERO_COPY>> is centered, in bold near-black sans-serif. The English text 'Open Data Hackathon' is slightly larger than the Japanese text above it.

Bottom band (~25% height):
- A full-width band colored in solid darker mustard-yellow #d8b021.
- Centered on this band, <<PERIOD_LINE>> in bold white sans-serif.
- Below it, a white rounded-rectangle pill-shaped button containing <<CTA_LABEL_1>> in bold near-black sans-serif.

Palette: mustard-yellow #f0c300, darker mustard-yellow #d8b021, bright green <<BRAND_PRIMARY_HEX>>, white, near-black #1a1a1a, dark-gray #585858, with purple and cyan accents from the background graphic.
Modern, tech-focused, and inviting feel for a data-centric competition. Typography crisp, no warping. Output: PNG.
