NEWS AND UPDATES - listing

----------------------------------------------------------------------------

/{locale}/news-and-updates
|
|
|
|
§5 of docs/SHARPER_Website_Draft_Section_EN_AR.docx. Two streams, exactly as
|
|
the draft describes them:
|
|
|
|
Tab 1 SHARP-ER News ?tab=sharper-news official project updates
|
|
Tab 2 From the Network ?tab=from-the-network updates submitted by CSOs
|
|
granted as part of the consortium,
|
|
each card crediting the
|
|
organisation
|
|
|
|
The tab values are the `news-article.category` enumeration in the CMS,
|
|
verbatim, so the query string and the Strapi filter cannot drift apart.
|
|
|
|
The tabs are LINKS, not client-side state: each stream is its own URL, so it
|
|
can be shared, bookmarked and crawled, and the server renders exactly what
|
|
the address asks for. `aria-current="page"` marks the active one.
