function createSlugResolver(
  slugMaps: Record<string, SlugMap>,
  defaultLocale: string
): {
  getLocalizedSlug: (category: string, canonicalSlug: string, locale: string) => string;
  getCanonicalSlug: (category: string, localizedSlug: string, locale: string) => string | undefined;
  getAllSlugPairs: (category: string, locale: string) => Array<{ canonical: string; localized: string }>;
}

Returns functions for resolving slugs between canonical (default-locale) and localized forms. When using createI18n, the first two functions are available from virtual:i18n.

`getLocalizedSlug(category, canonicalSlug, locale)`

Translates a canonical slug to a locale-specific slug.

Parameters:

Parameter	Type	Description
`category`	`string`	Slug map category (e.g., `'pages'`, `'saunas'`)
`canonicalSlug`	`string`	The default-locale slug
`locale`	`string`	Target locale

Returns: string — the localized slug, or the canonical slug if no translation exists

Examples:

getLocalizedSlug('saunas', 'model-165', 'es');  // "modelo-165"
getLocalizedSlug('saunas', 'model-165', 'en');  // "model-165"
getLocalizedSlug('pages', 'about', 'es');        // "sobre"

`getCanonicalSlug(category, localizedSlug, locale)`

Reverse lookup — finds the canonical slug from a localized one.

Parameters:

Parameter	Type	Description
`category`	`string`	Slug map category
`localizedSlug`	`string`	The locale-specific slug
`locale`	`string`	Source locale

Returns: string | undefined — the canonical slug, or undefined if not found

Examples:

getCanonicalSlug('saunas', 'modelo-165', 'es');  // "model-165"
getCanonicalSlug('saunas', 'model-165', 'en');   // "model-165"
getCanonicalSlug('saunas', 'unknown', 'es');     // undefined

`getAllSlugPairs(category, locale)`

Returns all canonical/localized slug pairs for a category and locale.

Parameters:

Parameter	Type	Description
`category`	`string`	Slug map category
`locale`	`string`	Target locale

Returns: Array<{ canonical: string; localized: string }>

Example:

getAllSlugPairs('saunas', 'es');
// [
//   { canonical: 'model-165', localized: 'modelo-165' },
//   { canonical: 'model-200', localized: 'modelo-200' },
// ]
