+# capture-studio-bin - Capture Studio by Tenzen Studio (https://tenzen.studio),
+# a proprietary Electron app for recording and editing product demos.
+#
+# Upstream publishes no source, so there is only this -bin package. For Linux
+# it ships nothing but a Flatpak bundle, versioned on its own download host:
+# the PKGBUILD unpacks that with ostree (a Flatpak bundle is an OSTree static
+# delta) and takes the icon out of app.asar, so the test build needs both.
+#
+# The release API names the current version and lists every artifact with its
+# sha256, so nothing has to be downloaded to refresh the checksum - makepkg's
+# test build verifies it against the real download anyway.
