/* Theme integration tweaks.

   These rules are designed to be safe with Furo's built-in light/dark modes.

   - PlantUML HTML embeds an inline `background:#...` on the <object>, which can
     clash with dark mode; override it to be transparent.
   - sphinx-needs "need" tables use their own backgrounds; align them with
     theme CSS variables so they follow the active theme.
   - Figure zoom is handled by figure-zoom.js + #osqar-lightbox styles below.
