/* ==========================================================================
   Tom's Building & Carpentry — London & surrounding areas
   --------------------------------------------------------------------------
   Red is his, off the van. Everything else is deliberately warm — oat, stone
   and timber — because the portfolio already has a red-on-white trades site
   (Guyva Brickwork, #c8202e on #ffffff) and two near-identical red builders
   would be hard to tell apart. Warm neutrals also suit the carpentry half of
   the business, which is the part that separates him from every general
   builder in London.
