{# Host status. A read-only view of one `cymatix-status` observation of
   THIS machine: whether the coding host on it is wired to cymatix. The
   collector builds `state.host_status` as a typed allowlist
   (collector.project_host_status) behind a bounded single flight cache
   (status_cache.StatusCache), so nothing here is a raw report: no path,
   no URL, no native config value, no error text and no arbitrary
   guidance string can reach this template.

   Two rules shape the markup.

   1. Every dimension renders on its own row, from its own vocabulary
      table. Reachable is not healthy, configured is not activated,
      installed is not enabled, and a registry record is not an
      authenticated connection. There is no roll-up badge, because one
      green light would claim exactly what this panel exists to keep
      apart.
   2. Freshness is not readiness. The freshness line and the
      `data-freshness` attribute describe the observation; the rows
      describe what that observation found. A stale or expired card
      keeps its values and loses its emphasis (launcher.css); it never
      rewrites a true into a false.

   A null group or a null tristate renders Unknown, never false. Nothing
   is safe-marked: the environment autoescapes .html
   (`app.py:_get_templates`) and the approved strings pass through it
   unchanged. The panel offers no control, no link and no repair action.
