/* shared nav + journey rail
------------------------------------------------------------------
Drop-in shared components for every member-facing page. These promote
the journey tracker already proven on dashboard.html into the shared
sheet (identical class names + values) so any page can reuse it.
1) Top-nav: the markup styled above IS the shared
nav; add class "active" to the current section's link to mark it.
2) .journey: a 4-step progress rail (Test -> Results -> Plan -> Retest).
Mark the CURRENT step with class "current" and every EARLIER step with
class "done"; leave later steps unclassed. Set those classes from Store
state (see the snippet note) — e.g. done once Store.results('baseline')
exists, current = the first not-yet-done step. */
