/* ============================================
   COACH-MARKS (tips)
   ============================================
   Inline tips anchored to UI elements, triggered by a first-time interaction,
   not idle timers.

   2026-10-08: the card IS the shared guide card (css/feature-tour.css
   .fr-guide-*), the same one the tour and Show me how use, so the three read
   as one feature. This sheet places it, fades it, and styles what a tip
   adds: Show me how's labelled pictures (BoardSpecimens) and drawn buttons.
