+fix: correct leaked type references in `Constraints`, `RadioInput`, and `ViewSwitcher` declarations
+
+Their published `.d.ts` referenced the aggregate `@commercetools-frontend/ui-kit`
+package, which isn't installed when you depend only on the granular
+`@commercetools-uikit/*` packages. That unresolved reference collapsed the
+affected prop types to `any`, surfacing as `TS7006` errors in strict
+TypeScript setups. The declarations now use in-package relative references, so
+the prop types resolve correctly. No component API or runtime behavior changed.

+# --- declaration-emit leak workaround (FEC-938) ---
+# `@commercetools-frontend/ui-kit` (the aggregate preset) is a root
+# devDependency because the .visualroute/bundlespec fixtures import it. Under
+# strict pnpm that puts a `node_modules/@commercetools-frontend/ui-kit` symlink
+# in place, and preconstruct's declaration emit then prefers that resolvable
+# bare specifier over the in-package relative path — leaking
+# `import("@commercetools-frontend/ui-kit").T...Props` into the published .d.ts
+# of the compound components (constraints, radio-input, view-switcher). Strict
+# consumers can't resolve it, so those prop types collapse to `any`.
+#
+# preconstruct does not need that symlink (the fixtures aren't part of the dts
+# program), so we hide it during the build to force the correct relative
+# specifier, and restore it afterwards (and on any exit).
