/* Interactive product tour (Spec 04). One real investigation, six steps.
   Progressive enhancement: without JS every step renders stacked and readable;
   tour.js turns the page into a stepper (one step visible, dots, arrow keys).
   Class prefix .tp- (tour panel) to stay clear of the trailer's .t- names. */
