// The [locale] mirror pages re-export the bare pages and add getStaticPaths,
// which tells `voltro build` which locale-prefixed paths to emit. The default
// locale (en) is NOT listed — it lives at the bare path. The docs [...slug]
// mirror is the interesting case: a DYNAMIC route under a DYNAMIC locale
// segment, so its getStaticPaths must emit the CROSS-PRODUCT of every
// non-default locale × every doc slug.
