# Use npm install instead of npm ci to avoid optional dependency bug
# better-sqlite3 will download pre-built binaries for the target platform
# Use cache mount to speed up repeated builds
# --legacy-peer-deps needed for vitest peer dependency conflicts
#
# PUPPETEER_SKIP_DOWNLOAD=true: puppeteer's npm postinstall downloads a
# Chrome binary, and Chrome has no armv7 build — without this the
# install fails at downloadBrowsers and the whole image build aborts.
# Puppeteer is a devDependency used only by CI tests, so production
# armv7 images don't need the browser binary at all.
