A square mark logo for "{{BRAND_NAME}}", a {{INDUSTRY}} product targeted at {{TARGET_AUDIENCE}}.

Style: {{STYLE_KEYWORDS}}. Modern, sleek, minimal, geometric, flat vector. Clean solid shapes, strong silhouette, instantly recognizable at 16x16 pixels (favicon scale). The mark must also work in pure monochrome — all meaning carried by shape, not color.

Colors: use only {{PRIMARY_COLOR}} as the dominant color and {{SECONDARY_COLOR}} as the accent. Transparent background. No color gradients, no drop shadows, no glow effects, no bevels, no 3D rendering, no photorealism, no textures.

Composition: centered, single-subject mark. Balanced negative space. Works equally well on light and dark backgrounds. Iconic, memorable, ownable — not a generic SaaS lightbulb / gear / rocket / mountain unless the industry specifically calls for it.

Vendor family context: {{VENDOR_FAMILY}}. Tagline (for brand voice only, DO NOT render text into the mark): "{{TAGLINE}}".

Negative prompt: NO text, NO letters, NO numbers, NO cluttered details, NO realistic illustration, NO watercolor, NO sketched lines, NO hand-drawn appearance, NO stock-photo tropes, NO rainbow gradients, NO purple-to-blue gradients, NO shiny plastic, NO chrome, NO neon glow, NO drop shadows, NO 3D perspective.
