   HOW TO SWAP: pick a font at fonts.google.com → "Get embed code" →
   "@import" tab → copy the URL into the line below → update the matching
   --font-* variable in :root. Done.
     Space Grotesk  → headings (geometric, technical, futuristic)
     Sora           → body text (clean, modern)
     JetBrains Mono → labels, tags, buttons (precise, technical)
