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.
