/* ============================================================
   theme.css — light/dark contrast fix
   Remaps Bootstrap utility classes to the page's theme tokens so
   text and backgrounds stay readable in BOTH light and dark mode.
   Without this, .text-white / .bg-black etc. keep their Bootstrap
   defaults (white text, dark panels) and wash out in light mode.
   Loaded after each page's inline <style> so these rules win.
   Fallback values match the dark theme, so pages that don't define
   the tokens keep their original look.
