+# Pull requests are squash-merged, so the title becomes the commit on main:
+# it must start with a conventional commit type, so that release notes can
+# be written from main's history (git-cliff, as lazysecrets does). Brackets
+# and a missing space are fine too.
+#
+#   feat: SOPS and .env files in git repos
+#   fix(search): ctrl+r with empty results loads the scope
+#   feat!: rename config keys          (! marks a breaking change)
+#   [feat] install with a one-liner
+#   [fix]: hide values on blur
+#   docs:split the README
