Module compose 

Composing a WESL module of the built-in shader package into WGSL.

Every built-in entry shader — lit, line, blit, fullscreen_vertex — is a module of the package generated at build time from shaders/*.wesl. This module is the one place that turns one of them into a WGSL string: it sets the conditional-compilation flags, keeps the module’s own entry points, and, when a caller extends a shader, mounts the spliced source in place of the package’s copy. Both the built-in pipelines and a caller’s own pipeline reach the same facilities here; nothing in the composition is private to one built-in implementation.
