The .xgis compiler pipeline: from style text to GPU programs

How a declarative map style becomes GPU work: lexer → parser → a Scene IR → optimization passes → codegen that emits typed shader-dsl IR (never WGSL strings), per-feature compute kernels for match(), and a gradient atlas for zoom-dependent paint.

X-GIS compiles a declarative style language into optimized WebGPU shaders — through a real compiler and a typed shader IR. Here's the shape of the system and why each layer exists.
