/* ==========================================================================
   lukasvarga.com — Design System
   Eco-brutalist, modern, tech-oriented. Light + dark theme.
   --------------------------------------------------------------------------
   HOW TO EDIT:
   - Raw palette + LIGHT theme tokens live in :root below.
   - DARK theme tokens live in [data-theme="dark"] right after.
   - Components only ever use semantic tokens (--bg, --ink, --border, ...),
     so adjusting a theme = editing one block.
