Minimalist Website Logo Design

I need a clean, black-and-white logo for my website "SHOPATO" that relies on our initials as the central graphic element. The look should feel minimalist—no extra flourishes, just strong negative space and balanced typography.

Here’s what I expect:
• One primary concept based on the site’s initials, supplied as a vector (AI/SVG) plus web-ready PNG and JPG.
• A simple horizontal and square version so I can use the mark in headers, favicons, and social profiles.
• Two quick rounds of minor tweaks on spacing, weight, or alignment.

Please create the design in Illustrator or an equivalent vector tool so the artwork scales cleanly. Keep to solid black on white (and vice-versa) with no additional shades; I’ll handle any color variations later. If you have recent minimalist logo samples, share a link so I can gauge fit before we start.
