/*
  Louis Tucker Digital
  Design direction: an editorial, ledger-like layout for a solo web developer.
  White ground, alternating with a subtly blue-tinted light grey, single
  navy accent used sparingly (primary button, links, one hero line).
  Archivo for headings, Source Serif 4 for body copy. No cards, no icon
  tiles, no gradients.

  Header is a light, understated bar rather than a solid colour block,
  and closing CTAs sit in a soft rounded panel instead of full-bleed
  colour, so the accent reads as considered rather than shouted.
