That is the seam this skin uses: we redefine Coder's OWN tokens rather than fighting its components with per-selector overrides. Colour needs almost no `!important` as a result. HARD CONSTRAINTS discovered in the running deployment (do not break these): 1. Coder writes `hsl(var(--border-default) / .5)`.
