Put news on the globe, with a feed panel in the right rail

Events ▸ News draws the last 24 hours of reports from curated hotspots
(Ukraine–Russia, Israel–Gaza–Lebanon, Iran–Hormuz, Yemen–Red Sea, Sudan,
Sahel) and developing situations elsewhere, from any server that answers the
`/api/news` read routes.

- Globe: one marker per merged event, clamped to the ground and culled at the
  horizon; one beacon per hotspot when zoomed out and a pulsing beacon for a
  developing situation; hotspot outlines with disputed areas dotted and
  labelled by who administers and who claims them; picture cards for at most
  ten major or fast-growing events with two or more sources, never
  overlapping, switchable off.
- Panel: hotspot chips, a severity filter (significant and above by default),
  categories, minor news off by default, and a scrolling list of event cards
  with picture, headline, place, sources, age and the sides that reported it.
  "In view" lists what is near the map below 3,000 km once the camera
  settles. A card flies the globe to its event and opens it with a link to
  the publisher. Reduced motion stops the pulse and the flights.
- Core serves no news itself: the local server proxies GEV_NEWS_ORIGIN when it
  is set, and answers 503 unavailable otherwise, so the layer reads "not
  configured" once instead of retrying.
- Share token 9 (enabled-only); voice stays off for this layer.

Core serves no news itself; the local server forwards the layer's `/api/news/hotspots`, `/feed` and `/outline` GET requests to the configured server | Each report stays its publisher's: headlines and summaries link to the original article, and pictures are hotlinked from the publisher's site (no referrer), never stored | Per report: publisher name and article link on every card; picture cards name the picture's publisher.

Links are matched best-effort by incident name and state, with incident page origin and update times checked on selection.
