# Verify packaged GUI artifacts are healthy before a release is declared done.
#
# Background: on 2026-08-28 (1.3.0) the host wine broke (missing syswow64, so
# wine -- the NSIS self-extract step -- failed), and electron-builder silently
# wrote a 264 KB installer shell that did NOT embed the 86 MB payload. No gate
# caught it, so a broken Windows installer shipped. This script is that gate.
#
# It enforces a per-artifact minimum size, so a degenerate installer (or a
# build that only emitted a shell without its embedded payload) fails loudly.
# A size check is the right signal here: a healthy NSIS exe is ~86 MB and the
# broken 1.3.0 one was 264 KB (326x) — electron-builder compresses the embedded
# app.7z, so a plaintext-payload string probe would be unreliable.
