/**
 * GE Low Voltage Switch Plate - Skeuomorphic UI
 *
 * Design goals:
 * - Replicate the look of classic GE despard-style switch plates
 * - Beige/ivory color scheme matching physical plates
 * - 3D rocker switches with realistic shadows
 * - Green highlight on top when ON, red highlight on bottom when OFF
 * - Two 2x4 plates side by side
