        // surface the worst offender (the feed's timestamps) sits on:
        //   neutral-500 #737373 → 3.98:1  (fails 4.5:1 — 67 uses)
        //   neutral-600 #525252 → 2.42:1  (fails 4.5:1 — the worst value shipped)
        // Overriding the ramp step here fixes every existing use and every
        // future one without a find-and-replace across the tree. Measured
        // again after the override, against term-gray:

        //   neutral-600 #8a8a8a → 5.47:1

        // draws text on, including the tightest case — neutral-600 on
        // term-sidebar-raised (#212327), the lightest surface it appears on
