/* ═══ R155 — THE COACH-MARK GUIDED TOUR, ported to the plan builder ═════════
   Byte-for-byte the same .coach-mask/.coach-ring/.coach-tip/.coach-close/
   .coach-kicker/.coach-title/.coach-text/.coach-progress/.coach-nav rules
   every earlier port (student.html, flashcards.html, qbank.html,
   messages.html, catalog.html) uses — see student.html's own big comment
   above .coach-mask for the full design rationale (real spotlights on real
   elements, a 4-piece dark mask with a genuine hole so whatever is
   highlighted stays clickable). Copied verbatim from catalog.html rather
   than re-derived or shared via app.js — no port of this tour shares its
   engine with another; each page owns its own copy, same as every earlier
   one. See the JS engine near the end of this file (buildTourOpen()) for
   why this page, like catalog.html/qbank.html, needs neither ensureSidebar()
   nor prepareStep(). */
