/**
|
|
* Builds a map of locale → URL for hreflang alternate links, suitable for
|
|
* Next.js Metadata `alternates.languages`.
|
|
*
|
|
* Bridges SEO and i18n: for each configured locale that the document has a
|
|
* slug in, it produces the locale-aware path (via buildLocalizedPath),
|
|
* optionally prefixed with an absolute origin.
|
|
*
|
|
* @example
|
|
* buildHreflangAlternates({
|
|
* slugs: { pl: 'o-nas', en: 'about' },
|
|
* config,
|
|
* baseUrl: 'https://example.com',
|
|
* })
|
|
* // → { pl: 'https://example.com/pl/o-nas', en: 'https://example.com/en/about' }
