Structure-routed visual compiler: recognize and automate GUIs in YAML
...You describe the interface in plain YAML: tokens are pictures matched under a discipline, lexemes their spatial arrangements, with OCR for the content that changes. On a match it drives the GUI (click, type, route text); the logic turns a recognized screen into what to do — a watched value with prose rules, or a neighbourhood rule table over a tiled grid. The shipped examples are pure grammar, no Java: a calculator automator and a Minesweeper solver. Java 21, MIT-licensed. See VANGA_DESIGN.md.
