Nervous System Workbook Builder turns a single regulation focus into a complete, sell-ready printable workbook specification. It returns a named 5-stage regulation arc, a sensory-diet planner system, a full page list, a tone-calibrated style guide and cover concept, an SEO-optimized title and description, 13 tags, paste-ready image prompts, and a print checklist for Etsy and Amazon KDP. The focus (high sensitivity/HSP, sensory overwhelm, emotional dysregulation, burnout reset, and more) is a runtime input you provide, so it adapts to any niche. Built for digital-product sellers who want a polished, ready-to-list product without starting from a blank page.
