 * in Node, through `@intlayer/babel`; the plugin only receives the resulting
 * tables and rewrites the matching source accesses
 * (`content.title` → `content.a`).
 *
 * The work is coordinated by a sentinel file: Next.js loads `next.config.*` in
 * several processes per build, and running the minify pass twice would derive
 * the aliases from the already-renamed dictionaries. Processes that lose the
 * race read the tables the winner cached.
