NEWS AND UPDATES - one article

/{locale}/news-and-updates/{slug}
|

|
|
Registered in app/routes.ts as "newsDetail", a SIBLING of the listing route
|
|
under the ":lang" layout, and typed against its generated `./+types/` module.
|
|
|
|
A "From the Network" update credits the submitting organisation on the page
|
|
and in the Article JSON-LD, because the draft is explicit that network
|
|
updates are attributed to the CSO that wrote them - the project must not
|
|
appear to be the author of somebody else's work.
