// Valid RGB/RGBA colors
infer('rgb(255, 0, 0)') // ✅ returns 'color'
infer('rgba(0, 255, 0, 0.5)') // ✅ returns 'color'
infer('rgb( 128 , 128 , 128 )') // ✅ handles spacing variations

// Invalid cases properly rejected
infer('rgb(300, 0, 0)') // ✅ returns 'string' (out of range)
infer('rgba(255, 0, 0, 2)') // ✅ returns 'string' (alpha out of range)
