Minimalist Icon-Only Logo

I need a clean, modern logo that relies entirely on visual form—no company name, no slogan, just a strong stand-alone mark. The aesthetic should stay strictly minimalist, and I’m leaning toward a mixed approach to the iconography rather than committing to a single motif; feel free to explore geometric hints, subtle natural cues, or abstract strokes as long as the final shape remains simple and memorable.

Please deliver:
• A primary vector file (AI or SVG)
• High-resolution PNGs on transparent background
• One light-on-dark and one dark-on-light variation

The design must scale well from 24 px up to large print sizes and hold its clarity in monochrome. I’d like to review two initial concepts, choose one, and go through up to two refinement rounds before final hand-off.
