+# Submits each new ScreenSound release to the Windows Package Manager
+# Community Repository (microsoft/winget-pkgs) as `twibster.ScreenSound`.
+# Once the first submission is merged upstream by Microsoft's reviewers,
+# users can install with:
+#
+#   winget install twibster.ScreenSound
+#
+# Trigger: `release: released` fires once, when release.yml publishes a
+# non-draft, non-prerelease GitHub Release. softprops/action-gh-release
+# in release.yml sets both flags to false, so every cut release kicks
+# this flow. Workflow_dispatch is additionally provided as an operational
+# retry lane — if the upstream PR needs to be re-opened (e.g. after the
+# PAT rotates or reviewers request changes), a maintainer can rerun
+# against any past tag without re-cutting the release.
+#
+# Required one-time setup (see README of the feat/winget-release PR):
+#   1. Fork microsoft/winget-pkgs to the twibster account.
+#   2. Create a classic PAT with `public_repo` scope.
+#   3. Add the PAT as repo secret `WINGET_TOKEN`.
+#
+# Why a classic PAT instead of GITHUB_TOKEN: GITHUB_TOKEN is scoped to
+# this repo, so it can't push manifest commits to twibster/winget-pkgs
+# (our fork) nor open a PR targeting microsoft/winget-pkgs. The action
+# needs a token tied to a user account with write access to both. A
+# fine-grained PAT works too but requires explicitly granting access to
+# the fork and to contents/pull-requests scopes; classic with public_repo
+# is the documented, low-friction path.
