Fixed interpolation‑variable errors in node‑sass/Hugo.

Started applying the --bs-border-radius variable to additional components.

Fixed the positioning of .tooltip-inner when using variations in fallbackPlacements .
Corrected the selector for dark‑mode carousel overrides that use $color-mode-type: media-query during compilation.

Updated RFS to version 10.0.0.
