+  // clamped to 12 — while the focus ring, drawn across the full width, keeps a
+  // true 20px curve. Same box, same declared radius, two different curves, and
+  // a visibly doubled edge down the left side. Under 12px nothing is clamped

+  // ring clamp to half the field's height, so they land on the same curve.
