Create a prompt to generate a logo for this brand. Decide the sign type and keep it simple/scalable. Return JSON {"prompt":"...","type":"...","negative":"..."}, where type is lettering, icon or combination.
Mechanics: the generator assembles an image from the density of features and does not hold fine details well - thin lines and microtext become blurred when reduced. The logo must be readable in 16 pixels, so the prompt should enhance simplicity. Levers: type of sign (lettering - letters/monogram, icon - symbol, combination - symbol plus name), concrete metaphor instead of abstraction, words “flat vector, minimalism, negative space, one or two colors, on a white background, centered.” Insider: ask for a sign WITHOUT text inside - models write letters with errors, add the name separately in the editor; and directly indicate “readable on the 16px favicon” - this forces the model to remove the unnecessary things. Second insight: the negative here solves half the problem. A common mistake: “logo for a coffee shop, beautiful, modern” produces a detailed illustration with gradients that falls apart when scaled down. We need: metaphor plus geometry plus a strict limit on colors and details.
