Lime text on the cream/white BG fails WCAG AA. Adds a foreground token that
is midnight by default and lime inside the .sidebar scope (which lives on
midnight). Rewires every text-color use of --color-accent to the new token,
including the double-fallback typo variants. Decoration uses (border, BG,
border-bottom) keep --color-accent (= lime).
mAi/paliad#2 (full dark mode) flips --color-accent-fg back to lime in one
place — no need to revisit every rule.
