Implementation guides for the rewrite
These pages explain the current engine authoring surface directly from the rewrite codebase. They are intended for business implementors who need to add or adapt window types without reverse engineering package internals.
Window construction DSL
A business-implementor guide to the current TypeScript `ElementDefinition` API, its primitives, and the helper-based authoring style used by the rewrite engine.
- What a custom window definition looks like
- Which primitives and helpers exist today
- Sample code for parameters, geometry, parts, glass, pricing, and registration
