wrappers.py compiles the library with CULTMATH_MAX_SITES defined as a sentinel no shader file spells, so the three
site arrays get an array length id of their own and spvedit.py converts exactly that constant to the overridable
specialization constant (default from the HLSL guard). A library array of literal length 128 keeps its own id and
stays a plain constant. build-glsl.sh gains the pipeline function and scratch variants: a macro outside a declarator,
a folded expression reaching the capacity id, and a non-site float4 x[128] parameter that a consumer's override must
not resize. The [128] shape arm goes: a non-site 128 array is legitimate output.
