-      metrics and the radius ladder already flow through the size table,
-      so each stop covers border + focus chrome (`Theme::borders`), the
-      spacing unit (`Theme::spacing`), and the component's stated dims:
-      button (the API template) first, then input, select, menu, popover,
-      dialog, toast, tooltip, alert, combobox, command palette, switch;
-      per-platform targets in
-      [platform-metrics-audit.md](platform-metrics-audit.md).

+- [ ] **Switch platform chrome** — stated track and knob dims
+      (`switch_height` / `switch_width` / `switch_knob`, inset and travel
+      derived); borderless knob.
