/* ==========================================================================
   Dealer invite — the scroll-triggered trade-account panel
   --------------------------------------------------------------------------
   Apple's material model, on the web:
     · a big surface reads as THICK — stronger blur and a deeper shadow than
       the small chips elsewhere on the site
     · a bright top edge is light catching the material
     · the surface MATERIALIZES (blur + scale together), it does not just fade
     · a modal task dims and pushes the page back; the scrim carries its own
       lighter blur so the page behind reads as depth, not as wallpaper
   Never stack two light translucent surfaces — the fields inside sit on a
   tinted solid, not on more glass.

   z-index: 124/125 — above the quick view (110) and the image overlay (120),
   below the toast stack (140) so a confirmation still reads over the panel.
