+- Keep the globe in view from orbit. Cesium's free look (Shift+drag) turned
+  the camera in place, so a few drags from the whole-globe view left only
+  stars, and the pose stayed in the share link. Free look now works only below
+  1,000 km, and above it a drag that starts on the stars orbits the globe
+  instead of turning the camera; a camera move that ends above it with no
+  planet surface in view (inside the scope keyhole when the scope is on) turns
+  straight down; and voice tilt and turns from orbit stop while the planet is
+  still on screen and say so instead of reporting a turn they could not make.
+  Thanks to [Chad Elliott](https://github.com/THEtheChad) for the review that
+  closed the drag path and kept authored scenes framed (Manjunath,
+  @manjunath22466, #1532).

+- Add Wildlife Sightings in the Wildlife layer group, off by default, using
+  keyless iNaturalist observations within 48 h (whales 7 d) and Acartia Salish
+  Sea marine mammals. CONFIRMED and taxa filters share via token `9`.
+  A noninteractive density glow accompanies real-sighting taxon badges,
+  decluttered species labels and credited ambient photos. Selection stays
+  pinned across camera and sample changes and opens an anchored photo card
+  with a contained image, creator/licence and one iNaturalist source link.
+  Obscured and Acartia sightings use text-only cards; private records and
+  Acartia comments are excluded. Attribution appears in the layer row and
+  Data attribution popover. Cached progressive tiles, bounded image/billboard
+  work and a paced queue preserve iNaturalist's 60/minute and 8,000/day limits.
+  All 11 locales supported. (lyehe, #1591)
