NTN resilience
When the ground network fails, a non-terrestrial path is only useful if you know what still works and what gets worse.

Scenario outputs are simulations. They are not an on-orbit measurement or a satellite service-level agreement. measured_topology is not recorded as true.
Current is shown first. Future and legacy stay labeled. A rendered SVG is used when accepted main already committed one. Otherwise the Mermaid or Markdown source is shown and is not executed in the browser.
