/* Mall Tile Field — Low-chrome discovery surface
   Portrait-first 9:16 video wall (Shorts-style)
   SoftProto mount point: #mallTileField[data-softproto-mount="tile-field"]

   Anchor model: This is the MIDDLE FIELD — dominates the Mall experience

   Motion modes:
   - Snap (default): page-style discrete movement
   - Glide: fluid scroll override

   Density presets (AI-controlled or viewport-adaptive):
   - 3x4, 3x5, 4x6, 5x8 (portrait-first dense walls)
   - 6x3 (desktop wide viewport - auto-selected for fine-pointer + landscape)
