Signature Milestone — First YURI1 AI Music Tech Decision

This milestone commemorates an early technical decision in the development of AI music generation for YURI1.

During the initial exploration of local, prompt-driven music generation, YURI1 sought a solution capable of producing both short looping background music and full-length songs.

In response to these requirements, GPT Work recommended ACE-Step 1.5 as a potential solution. This recommendation marked an important step toward establishing the AI music-generation technology that would later support YURI1's music production.
