/*
 * Homepage request journey (partials/home/features.leaf: nav.fk-jr), between
 * the "How it works" intro and chapter 01. Four linked stops (Collect, Vote,
 * Triage, Notify), each with a small Trailmate mockup, joined by a track.
 *
 * Two ways it renders, and both are complete:
 *   1. No script, reduced motion, or motion.js absent: the markup as written,
 *      which is the FINISHED state. Track full, every node lit, the title
 *      typed, TestFlight on the chip, the email in the inbox. Elements that
 *      exist mid-sequence (data-jr-until) are hidden.
 *   2. html.fk-motion (motion.js) + .fk-jr.is-live (home-journey.js): stops
 *      ahead of the current one show their opening state, the current one
 *      plays (.is-on, beats 0-3), stops behind it hold the finished state.
 *      --jr-p (0 to 1) drives the fill and the travelling marker.
 * Only transform and opacity animate. Colours are --fk-* tokens; status chips
 * reuse .fk-chip--* from story.css. --jr-* names are component internals.
