/* KJ Engineering & Consulting
   Brand: logo maroon on white, steel and charcoal neutrals taken from the hero photograph.
   Layout: white logo header, full-bleed photo hero with a dark caption band, then a two-column
   introduction and full-width content bands on a 1180px container.
   The site commits to a single light look so the maroon logo always sits on white. */
