+# WARNING: This module was "vibe coded" by Claude Sonnet 4.5 Thinking
+# Nix modules are mostly boilerplace, so the logic is (mostly) mine, and the
+# rest comes from Claude. For reference, here was my prompt:
+#
+# I would like to write a new module for managing MacOS apps via the `defaults`
+# cli. Ideally, the syntax that I want to include in my home-manager config
+# should look like:
+#
+# ```nix
+# darwin-defaults = {
+#   "com.fpfxtknjju.wbgcdolfev" = {
+#     centerTasksAndButtons = false;
+#     pinList = [
+#       { action = "finderNewWindow"; bundleIdentifier = "com.apple.finder"; }
+#       { action = "firefoxNewWindow"; bundleIdentifier = "org.mozilla.firefox"; }
+#       { action = "launchOrActivateApp"; bundleIdentifier = "com.electron.logseq"; }
+#     ];
+#   };
+#   "com.lwouis.alt-tab-macos" = {
+#     screenRecordingPermissionSkipped = true;
+#     nextWindowGesture = 1;
+#   };
+# };
+# ```
+#
+# This should be fairly easy to implement, as `defaults` accepts (escaped) plist
+# strings, and Nix provides lib.generators.toPlist. Can you help me write the
+# module, please?
