/* ---------------------------------------------------------------- Wizard mobile fixes (Oct 2026)
   1. The step slide-in kept an active transform ("both" fill), which made the card the containing block for the
      position:fixed action bar, so the bar sat over the tiles. Only fill backwards, so nothing lingers.
   2. Tile steps (only "Back") get a plain inline Back link, not a fixed bar.
   3. Steps with a primary button (postcode, contact) keep a sticky action bar at the bottom of the screen.
   4. The sidebar summary is hidden on phones; the step itself shows what is needed. */
