     var(--color-background-secondary), --color-toc-item-text is
     var(--color-foreground-secondary), and so on — and then re-declares only the
     BASE variables for dark mode. A literal light value written here is therefore
     never overridden, and the sidebar stays light while the page goes dark.
     So: derive from the same bases furo does (they already follow the theme), and
     give the few genuinely light-specific literals a dark counterpart at the
