This handles rendered PNG/SVG output when you need actual images, not text diagrams. It wraps Nano Banana Pro for Gemini to generate visual ERDs, UI mockups, wireframes, and architecture illustrations with a Salesforce aesthetic. The workflow is sensible: draft at 1K first, iterate with edits to avoid burning tokens, then render final at 2K/4K once composition is locked. It includes interview mode questions for ERDs and mockups, delegates text diagrams to the Mermaid skill, and has specific guidance for the architect.salesforce.com visual style. The prerequisites gate and error recovery steps are practical. Use this when you need slide-ready or documentation images, not when Mermaid syntax is enough.
