WGSL_BUILTIN_TYPES
상수, 레이아웃 분류
The type each @builtin(<name>) supplies, for every id WGSL gives one fixed type.

Read it
to check a declared field against what the pipeline will actually hand the shader, or to
render the vocabulary in a tool. builtin resolves its own token from this table
when the call omits one, so the table and the authoring surface cannot disagree.
clip_distances is absent on purpose: it is an array<f32, N> whose N the author picks,
so it has no single type and its builtin call still names one.
