Modern Golden-Ratio Poster Design

I’m preparing a clean, modern poster that must be built around the golden-ratio grid from the very first sketch to the final exported file. The entire composition—not just a single icon—should align to φ so the eye is naturally led through the piece.

Here is what I need from you:

• A modern, minimalist aesthetic: think generous white space, precise geometry, limited colour palette, and typography that complements the ratio rather than competing with it.
• Vector-based artwork created in Illustrator (or an equivalent tool that keeps the grid editable).
• Final files delivered as an editable .AI plus print-ready PDF at 300 dpi in both A2 and A3 sizes.

I’ll provide the specific copy and any brand colours once we start. Please show examples of past work where you have visibly employed the golden ratio or similarly strict layout systems—this is critical acceptance criteria. Looking forward to seeing how you can make mathematics look effortlessly elegant.
