 * English is the source and keeps the canonical URLs (/displays). Every other
 * locale is a prefixed mirror pointing at the matching file that
 * scripts/build-pages.mjs emits under /landing/<locale>/.
 *
 * Generated rather than hand-listed: this table is already the single source of
 * truth for routing, and a second hand-maintained copy per locale is a list
 * that goes stale the first time someone adds a page.
 *
 * Skipped deliberately:
 *  - transactional entry URLs (email links, the app clip, the ET client). Those
 *    strings are embedded in already-sent emails and shipped clients, so a
 *    locale prefix buys nothing and the surface is not marketing copy.
 *  - "/" and "/ja", which are the home page itself, already listed above.
