/* ============================================================
   Gottschalk Group LLC — company site

   AFTER EDITING THIS FILE: bump the version in index.html
   (company.css?v=2 -> ?v=3) before uploading. The server sends
   this stylesheet with a long cache lifetime, so without the bump
   returning visitors keep the old CSS against the new HTML — which
   silently renders the page with unstyled markup.

   Standalone stylesheet. Palette sampled from the logo artwork:
   navy #00124d, brand blue #013581, bright blue #1389de, silver #999a9b.
   Light theme by design: the logo is navy-on-white, and the company
   should read differently from the dark product site.
