# Triggered on tag push (v*) — builds release binaries across desktop targets,
# the WASM bundle, and uploads them to a GitHub Release draft. Step 1a kill-spike
# only ships `openpencil-app` (a placeholder binary entry); real desktop apps
# (DMG / AppImage / EXE installer) come in Step 1f and replace this scaffolding.
