Script quality pitiful. Created tool to generate them by analyzing browser events.

Stack: C# WinForms host, WebView2 browser, Scintilla.NET editor.

Data structure: twin lists--one for events, one for text.

Implementation:

 - Interception: Injected JS hooks + internal browser events.
 - Transformation: Event → Token → Instruction table → String.
 - Optimization: Toss unnecessary clicks, squash input events.
 - Rendering: Two-way binding between text and Scintilla editor.

NOTE: Lists desync on manual edits; blocks optimizer. Replace lists
with ASTs.

Script generation: minutes/hours → seconds.
