+- Add a Prohibited & Restricted Airspace layer for FAA prohibited (P) and
+  restricted (R) special-use airspace. The keyless `/api/drone-airspace` proxy
+  pages the public SUA FeatureServer, keeps a one-hour snapshot, and serves
+  stale data when a refresh fails. Zones draw as ground polygons (red
+  prohibited, orange restricted); selection shows name, altitude range, times
+  of use and agency, and the row legend states the layer is informational only
+  and does not include the UAS Facility Map or UAS flight restrictions. Off by
+  default; share-link token `8` (mvanhorn, #1086).

+- Add Houston traffic cameras from Houston TranStar as a CCTV pack. The camera
+  list is one keyless JSON request to
+  `traffic.houstontranstar.org/data/layers/cctvSnapshots_json.js`; frames are
+  stills synthesized from each numeric camera id on `www.houstontranstar.org`,
+  so a catalog field cannot steer the proxy off-host. Cameras without a
+  snapshot id, and cameras outside Greater Houston, are dropped. TranStar's
+  `dir` field (the side of the freeway the camera sits on) seeds a
+  low-confidence heading along the nearest lanes' travel direction. TranStar's
+  Content Usage terms (traffic.houstontranstar.org/disclaimer.aspx) prohibit
+  copying, distribution and external framing of its images without TxDOT's
+  written permission, so the pack is off by default; operators should set
+  `CCTV_HOUSTON_ENABLED=1` only if they hold that permission. Frames are
+  relayed on demand with `no-store` and not archived. Once enabled, it loads
+  the 250 cameras nearest downtown, Uptown, the Medical Center, IAH and
+  Galveston; `CCTV_HOUSTON_MAX_SOURCES` changes that cap.
+  Snapshots update about every 3 minutes. The catalog-wide ceiling is
+  unchanged; extra cameras share it round-robin with the other packs
+  (mvanhorn, #1125).

+- The Global Context range ring pulses like a sonar: three dim rings with a
+  soft inward glow grow from the subject to 250 km, and the ring flashes as
+  each one arrives. Flights, military aircraft and AIS vessels a pulse crosses
+  get a brief echo around their brackets. The pulses run for about 9 s after
+  a selection or camera move, dimming the ring between flashes, then rest
+  with the ring steady on screen, so a parked view stops repainting. Under
+  reduced motion there are no pulses and the ring stays on screen
+  (manjunath22466, #1519).
