   6 · QUESTIONS — THE PAY RUN
   Not a list. A conduit with four gates on it. One purple bar is
   the run; it advances left to right and every gate it reaches
   flips PENDING to CLEARED, its shutter lifts and a pink tick
   lands. Two inherited custom properties carry the whole device:

     --f   0..1  how far the run has travelled through THIS gate
                 (the gate sits at the halfway mark of its segment,
                  so it clears at --f = 0.5)
     --on  0|1   cleared

   Both default to 1. That is the progressive-enhancement contract:
   no-JS, reduced motion and mobile never touch them, so the run
   reads as finished and all four questions sit at full contrast.
   Only the live choreography knocks them down to 0.
