/**
 * i18n feature — gates the locale-prefixed page set.
 *
 * Locked manifest (#2653 Decision 4, i18n addendum): "i18n ON adds
 * `pages/[locale]/docs/[[...slug]].tsx` (the additional-locale doc route stub)
 * … No other pages." That ONE self-contained stub — retained as an explicit
 * host-owned route seam; zfb 2.13.1 also serves injected dynamic routes in dev —
 * is shipped under `templates/features/i18n/files/pages/[locale]/docs/`
 * and copied by `composeFeatures → copyFeatureFiles` whenever `i18n` is
 * selected. The old `pages/[locale]/index.tsx` home-route template is GONE
 * (the locked manifest doesn't want it — the package-owned `/` route
 * already handles every locale via `[[locale]]`-style resolution inside
 * `routes/index.tsx`'s own logic).
 *
 * No injections: the stub iterates `settings.locales` at build/request
 * time, so no postProcess regex patching is required for non-default
 * locales. Additional-locale content mirrors under
 * `src/content/docs-<lang>/` are seeded by `scaffold.ts`.
 *
 * Loud-failure check: per spec-lock Decision 8 (#1737), abort scaffolding
 * if the feature template dir is missing or empty. Without this guard,
 * `copyFeatureFiles` silently no-ops on a missing dir (l-lessons line 790)
 * and the user receives a half-scaffolded project with `i18n` enabled in
 * settings but no `[locale]/**` pages.
