Compiler pipeline
source → lexer → tokens → parser → AST → JS codegen → Web Worker
This is compilation, not direct AST interpretation. Programs have a three-second safety limit and cannot access the page DOM.

Library compatibility
Browser-safe headers use JavaScript shims. Hardware, OS, CUDA, raw socket, and desktop-window headers are recognized but require native cspc.
