Neutralize the app modal backdrop's dim/blur while the tour runs so a
ringed sidebar/toolbar control behind an open modal (steps 2, 10) stays
readable — the overlay's SVG spotlight is now the single source of
dimming. Add a walkthrough-running body class toggled by the overlay and
a CSS rule stripping [data-slot=dialog-overlay] background/backdrop-filter.
Also refine coach-card placement: dialogCardPosition drops the card into
the empty bottom-right corner for large modals (inventory, scan history)
and beside small modals, so it never covers modal content (steps 3, 4).
