/* Theme integration tweaks.

   - Furo already provides built-in light/dark modes.
   - PlantUML HTML embeds an inline `background:#...` on the <object>, which
     clashes with dark mode; override it to be transparent.
   - sphinx-needs “need” tables use their own backgrounds; align them with
     Furo's CSS variables so they follow the active theme.
