/**

 * @name Hreflang code mapping
 *
 * @description
 * Pure helper that maps file-suffix language codes (the suffix used in
 * filenames like `…_no.html`) to BCP-47 hreflang codes (Norwegian uses
 * `nb`). All other codes pass through unchanged. Identical contract to
 * `sitemap-xml/hreflang.ts` — the duplication keeps each bounded
 * context self-contained.
 *
 * Round-6 split: extracted from `scripts/generate-rss.ts`.
