PUBLICATION NOTE / OCTOBER 18, 2026 Hoydich Play / SIGNALSAURS concept edition, published on PointCast at https://pointcast.xyz/hoydich-play/ Research and concept work are dated October 17, 2026. The included records describe the pre-publication stage on that date. Historical statements about no public page or publication apply to that archived stage; this publication does not establish a working toy, AI implementation, supplier quote, legal clearance, partner commitment or product available for purchase. All product images are concept visualizations. Costs, prices and schedules are planning assumptions. No commercial trademark/design clearance is asserted. Third-party and user-supplied images in the brand book remain labeled as references. California AI-toy classification and other product requirements need specific review. The public brand-book PDF uses web-optimized embedded images to meet hosting limits. Its 20 pages and text are preserved. Five selected full-resolution PNG creative assets are also supplied separately and in the complete ZIP. No fonts are included; confirm commercial usage and outline final marks as needed. The original supplied package is preserved locally; public TXT copies include this dated publication context. No additional outreach or product launch occurred.
