Visual Detection Spec: Screenshot-Based Scene and Sprite Identification

docs/ps1/visual-detection-spec.md

This is the website shelf page for docs/ps1/visual-detection-spec.md. It exists because the project has hundreds of Markdown files and the website should not pretend the interesting work only happened in the polished essays.

Why this file matters

Active PS1 reference. This is active engineering documentation for the PS1 port. It is close enough to the code that stale claims here become real bugs.
