Academic Social Post Design Needed

I need a single graphic post created for a secondary-school audience (ages 11-17). The post will deliver educational content, so it must balance clarity with visual appeal—think clean, professional lines rather than playful cartoons or highly abstract art.

I will supply the topic outline, school logo, and brand colors as soon as we start. You translate that into a ready-to-publish square image suitable for Instagram and Facebook, plus the editable source file so the staff can update dates or text in the future.

Deliverables:
• 1080×1080 px final image (PNG or JPG)
• Layered source file (PSD, AI, or Figma)
• Fonts and any linked assets

Please keep copy legible at mobile size, respect the brand palette, and include space for a short caption beneath the visual. If anything is unclear, feel free to point it out before you dive into design; I’d rather answer questions early than revise later.
