   SHOWROOM HERO + BRAND/MODEL GRID (v2.1 - Transparent Overlay)
   ================================================================
   
   The brand logo grid overlays the RIGHT WALL in the showroom base image.
   The base image already has white panel tiles - we do NOT draw our own.
   Our overlay is TRANSPARENT; only the logos are visible.
   
   ALIGNMENT TUNING:
   If logos don't align with wall panels, adjust these values:
   
   .showroom-grid-wrapper:
     top, right, width, height  → Position the grid area over the wall
   
   .showroom-grid:
     rotateY      → Wall angle (more negative = angled further right)
     rotateX      → Vertical tilt
     skewY        → Trapezoid correction for perspective
     transform-origin → Pivot point
   
   .showroom-grid.brands-grid:
     gap          → Space between tiles (match wall panel gaps)
     padding      → Edge inset
   
   .tile-inner:
     padding      → Logo size within tile (less padding = bigger logo)
   
   DEBUG TIP: Uncomment "outline" rules to see boundaries.
