"""The SOP wizard's step rail — A4 / S9 / C1 (T5.1).

The rail was ten div elements carrying onclick inside a horizontal scroller: not
in the tab order, unreachable by keyboard, and silent about progress. The one
thing on the page that did say where you were was a "1 / 10" pill in the app bar,
detached from the control it described.

Every one of T5.1's done-whens is checked here, because nothing that already
existed could check any of them:

  1. every step is a <button> element (ten until T5.4 appended Locations)
  2. the rail is operable by tab, arrow keys, Home/End, Enter and Space
  3. the current step is exposed with aria-current
  4. complete / current / unavailable are distinguishable WITHOUT colour
  5. the "1 / 10" counter is gone
  6. the app-wide div-with-onclick count dropped by 10 against the wave 0 baseline

and two things that are not on the list but would make the rail a liar:

  7. the rail and validateStep() agree about which steps are open
  8. no path through the rail reaches a native dialog

Note (7): the reachability rule is deliberately the guard's own rule — you may
leave the step you are on once its required fields are filled — and NOT "lock
everything after the first unmet gate anywhere". The guard has never enforced the
second, so a rail that drew it would show a padlock the Next button walks past.

Trap: window.alert and window.confirm are stubbed before anything is driven. A
native dialog does not fail a headless CDP session, it HANGS it, which reads as
"the browser would not start" three minutes later.

Exit 0 all passed, 1 a failure, 2 could not run.
