/* Surgalt.dev — Bootstrap 5 theme overrides + the handful of components
   Bootstrap has no equivalent for (video player controls, the app-style
   mobile bottom tab bar). Everything else in the site is built directly
   from Bootstrap's own grid/utility/component classes in the templates -
   see static/vendor/bootstrap/. Bootstrap 5.3 ships its component colors
   as CSS custom properties, but most components set their *own* literal
   hex values rather than referencing the shared --bs-primary token, so
   re-theming without a Sass build means overriding both the shared
   tokens and the handful of components that hardcode them.
