# Archive existing publish/*.jpl builds before a new `npm run dist`.
#
# Per CLAUDE.md: never overwrite a previous .jpl. This moves each current
# publish/*.jpl into build-archive/ with a version + timestamp suffix so a
# fresh build can't clobber the last one. No-op when no .jpl is present.
#
# The archive lives at repo root (NOT under publish/) deliberately: webpack's
# buildMain step runs `fs.removeSync(publishDir)` and would wipe an in-publish
# archive, and `package.json` "files": ["publish"] would ship it to npm.
# build-archive/ is git-ignored and outside both.
#
# Wired as the `predist` npm script, so it runs automatically before every
# `npm run dist`. Safe to run manually too.
