+   The -fg tokens are a badge's TEXT colour, added because the ladder used its
+   raw hue as text on a 12% tint of the same hue — measured 1.60-2.97:1 on the
+   dark palette against the kit's AA floor of 4.5. Each is the hue mixed toward
+   --fs-text-primary until it clears 4.5:1 worst-case over surface-raised and
+   surface-hover in BOTH modes. Mixing toward that token is what makes one
+   declaration cover both: it inverts, so the text follows the mode.
+
    Only 12 tokens differ between modes. Everything else — spacing, type, motion,
    radius, and every derived colour — is stated once, because a value built with
    var() resolves where it is USED, not where it is written.
