/* ==========================================================================
   Guide card + board tour (v11, 2026-10-08)
   --------------------------------------------------------------------------
   .fr-guide-*  The ONE card used by the tour, tips (coach marks) and Show me
                how. Same type, buttons, progress and caret everywhere, so the
                three read as one feature. Owner-approved mock:
                claude.ai/artifact/Y9giWxjwt4ViV8iRqtAE5o.
   .ft-*        The tour's spotlight on the live board (js/ui/feature-tour.js).

   The v10 slideshow (chooser, 16 topic slides, screenshots, 17 diagrams) and
   its ~5,000 lines of styles were removed with it.
