Build the og:locale + og:locale:alternate[] block (newline-joined <meta> tags). Open Graph requires the og:locale for the page itself and one og:locale:alternate for every other supported language — defining the alternates lets Facebook / LinkedIn pick the best-fit locale at preview time.
Pure — no template literal interpolation beyond the static OG-locale map, so the output is deterministic across runs.
