+# NOT electron's dev.openpencil.app, so the Electron and Rust apps can
+# coexist without fighting over file-association ownership.
+#
+# ─── Local-verification caveats (2026-06-10, macOS dev machine) ────────────
+# Verified locally:
+#   * bash -n on scripts/bundle-macos.sh, package-deb.sh, package-appimage.sh,
+#     package-linux-common.sh
+#   * YAML parse of this file
+#   * package-deb.sh --layout-only and package-appimage.sh layout dry-runs
+#     with stub binaries (payload tree, control file, desktop entry, mime XML)
+#   * appimagetool 1.9.1 pinned release assets (x86_64 + aarch64) exist
+#     (checked via GitHub API); cargo-bundle `--target` flag confirmed
+#     against upstream source (present since v0.9.0)
+# NOT verifiable locally — needs a real tag-push CI run:
+#   * makensis compile of scripts/package-windows.nsi (no makensis on macOS;
+#     NSIS is preinstalled on windows-latest per the runner-images manifest)
+#   * actual AppImage assembly (appimagetool is a Linux ELF; it also
+#     downloads its type2-runtime from GitHub at pack time — needs network)
+#   * dpkg-deb --build (no dpkg locally; only the layout path was dry-run)
+#   * cargo-bundle bootstrap + `--target` bundling + hdiutil DMG creation on
+#     the GitHub macOS runner
+#   * installer smoke tests (NSIS install/uninstall + HKCR assoc, deb
+#     postinst mime refresh, AppImage launch, DMG mount + Gatekeeper)
+#
+# The `build` job builds the real `op-host-desktop` crate (winit + skia-safe
+# runner that drives the Rust editor); its shipped executable keeps the

+# `op`) is built in the same cargo invocation. The wasm web bundle is

+;   openpencil.ico          icon used by shortcuts + the .op/.pen ProgID
+;   Uninstall.exe           uninstaller (registered in Add/Remove Programs)
+;
+; File association: ProgID "OpenPencil.Document" under HKCR with DefaultIcon
+; and an open command, claimed by .op and .pen. Writing the machine hive
+; requires elevation, hence RequestExecutionLevel admin + $PROGRAMFILES64 —
+; an intentional divergence from electron-builder's per-user install
+; (perMachine: false): a per-user HKCU\Software\Classes claim silently loses
+; to any pre-existing machine-level registration. `.fig` is deliberately not
+; claimed on Windows (macOS-only association, parity with electron-builder's
+; fileAssociations list which only covers .op).
+;
+; Compile (relative paths resolve against this script's directory, so the
+; workflow passes absolute /D defines):
+;   makensis "/DVERSION=0.8.0" "/DARCH=x64" ^
