+ * Shared role chip — used by My Shares (and any other surface that
+ * needs to display a permission role with consistent styling).
+ *
+ * Produced by `formatRoleChip(role)` / `buildRoleChip(role)` in
+ * `components/roleChip.js`. Three tiers:
+ *
+ *   manage → orange (admin)
+ *   edit   → blue   (editor)
+ *   view   → muted  (viewer)
+ *
+ * Sized to match `.expiry-chip` so the role and expiry chips line up
+ * visually side by side.
