   Carr Detailing - site styles
   Hand-written, no framework. The palette is taken from the logo: chrome
   silver on near-black, with the steel blue of the water spray as the accent.
   (The spray samples at roughly #7190AE; the accent below is the same hue,
   pushed brighter so buttons still carry contrast.) Dark only - no light
   variant, because the logo is built for a dark ground.
