/* =====================================================================
   ONBOARDING TOUR (Aug 2026) -- scripts/onboarding_tour.js
   -----------------------------------------------------------------------
   A brand new user (company owner via verify_magic_link.php, or an
   invited team member via join.php) used to land on the dashboard with
   zero guidance -- no idea what a filter does, that Table/Kanban are two
   different views, or where the mega menu lives. This is the visual
   layer for the step-by-step spotlight tour that now walks them through
   it once, right after their first-ever login (?tour=1).

   Built custom (no new dependency) to match this app's own existing
   premium look -- same CSS custom properties (--td-primary etc.) and
   card/shadow language already used throughout header.php/style.css,
   rather than pulling in a generic tour library with its own separate
   visual identity.
