A minimalist logo mark for a Shopware 6 plugin called "Multi-Brand Layer". Three rounded rectangles stacked in a staircase pattern from bottom-left to top-right, each offset diagonally from the one below by roughly 20 % of the card's width. Bottom-left card amethyst purple `#7C5BA5`, middle card forest green `#3E6B4E`, top-right card sky blue `#8FB8CE`. Each card is a perfect square with 40-pixel rounded corners, upright (no rotation). Cards rendered at 82 % opacity so overlaps blend visibly. Composition: centred on a 1024 × 1024 pure white canvas with at least 18 % whitespace margin around the stack. No outlines, no gradients, no drop shadows, no text. Flat, tech-product aesthetic — think Linear, Notion, Raycast icon style. Recognisable at 48 × 48. Pure white background.
