ASW tokens referenced --gray-13, --gray-14, --gray-15 which don't
exist in Open Props (stops at --gray-12). All text and surface
colors resolved to nothing — invisible text in light mode.
Remap: 13→10, 14→11, 15→12.
postcss-import requires ALL @import statements before any rules.
The :root {} override block between Open Props import and layer
imports caused all 11 layer files to be silently dropped — only
Open Props variables made it through (29KB of definitions, zero
actual styles).
Fix: move :root overrides after all imports. Add explicit PostCSS
build step to deploy.sh (Hugo Pipes runs from a temp dir that
breaks relative paths anyway).
Result: 102KB compiled CSS = Open Props + all ASW layers.
