/* =========================================================
   Domenic Bosin — portfolio site
   Design language: "developer console" — terminal hero, bento
   grids, monospace accents. No external dependencies.

   Palette: anchored on the teal (#1B6B6B) already used as the
   brand color on the live site, with a warm gold as a sparing
   secondary accent instead of a fully warm scheme.
