/* ============================================================
   ONE CARBON — Main Stylesheet
   Style: Clean Minimal · DM Sans + Outfit · Stone + Emerald
   ============================================================

   COLOUR VARIABLES — edit these to retheme the whole site:
   --accent      : buttons, highlights, links
   --bg          : warm off-white page background
   --surface     : pure white (cards, nav)
   --text        : near-black body text
   --text-muted  : mid-grey secondary text

   ORIGINAL COLOURS (teal-green theme):
   --accent:       #1a7a6b
   --accent-dark:  #145f54
   footer-logo span (hardcoded): #5ab89e

   ORIGINAL FONTS (Jake + Claude, pre-boss changes):
   Headings: 'Fraunces' (Google Fonts) — elegant italic serif
   Body:     'Figtree' (Google Fonts) — clean geometric sans
   To revert: swap DM Sans → Fraunces and Outfit → Figtree in font-family declarations,
   and update the Google Fonts <link> in each HTML file accordingly.
