Routing

All unknown URLs are redirected to index.php by .htaccess. The router parses the URI and dispatches to the correct template.

`parseRequestUri(): array`

Reads the url_slug_* values from the active locale, splits the URI into segments, and applies these rules:

Segments	Pattern	Result
(empty)	—	Homepage
`{plural_slug}/`	e.g. `projects/`	Content type list
`{cat_slug}/`	2+ segments, prefix = category slug	Category page
`{tag_slug}/{name}/`	—	Tag page
`{type_slug}/{slug}/`	Article or page without category	Single content item
`{type_slug}/{cat…}/{slug}/`	Project with hierarchical category	Single project

Returns a normalised routing array: [type, slug, category, tag].

Localised URL slugs

URL prefixes are defined per locale in the lang files:

"url_slug_article":  "article",
"url_slug_articles": "articles",
"url_slug_project":  "project",
"url_slug_projects": "projects",
"url_slug_page":     "page",
"url_slug_pages":    "pages",
"url_slug_category": "category",
"url_slug_tag":      "tag"

These keys drive URL generation (cleanUrl()), admin URL generation (admin_content_url()), and route parsing (parseRequestUri()) simultaneously.
