/* ---- Bootstrap reboot compat ----
   Bootstrap (bundled via Vite) sets `body` bg/color from its own `--bs-*`
   custom properties and never switches colour mode (there is no
   `data-bs-theme`), so its reboot — loaded after this file — painted the body
   white and text dark in dark mode. Point Bootstrap's vars at the theme and
   win the `body` rule on specificity so the `[data-theme]` system owns the
   base surface. Higher specificity than Bootstrap's `:root`/`body`, so cascade
   order does not matter. */
