SaaS Dashboard Hero Illustration for Landing Pages

CopyROLE: You are a product marketing illustrator creating a hero visual for a [PRODUCT_CATEGORY] SaaS landing page. CONTEXT: The brand voice is [BRAND_TONE] (e.g., calm, technical, playful) and the primary accent color is [ACCENT_COLOR]. TASK: 1. Design a stylized, semi-abstract dashboard scene suggesting [CORE_FEATURE] without legible fake numbers. 2. Specify the composition: floating UI cards, depth layering, and focal hierarchy. 3. Define the lighting and material style (glassmorphism, flat, soft 3D) matching the brand tone. 4. Reserve a clear negative-space zone on one side for headline overlay. 5. List the limited palette derived from the accent color. CONSTRAINTS: No real logos, no readable invented data, no cluttered charts. Keep it on-brand and uncluttered. OUTPUT FORMAT: One image prompt paragraph, then 'Overlay Zone' note specifying which side stays empty and its approximate proportion.
