   SITE STYLESHEET
   Design concept: a personal workshop + notebook. The nav looks like the
   tabs on a binder — Home / Workshop / Notebook — that pull the page
   forward when active. Warm paper background, brass + teal accents.

   EDIT COLORS HERE — everything on the site pulls from these variables.
