# Install yarn dependencies
# -------------------------
# The git-sourced @replit/codemirror-* deps are prepared with Yarn Classic,
# whose cache lives in /usr/local/share/.cache/yarn. We mount that as a *tmpfs*
# (fresh every build) rather than a persistent BuildKit cache: when it was
# persistent, BuildKit would garbage-collect/evict part of it between builds,
# leaving a half-populated cache that Yarn Classic then tripped over (missing
# .yarn-tarball.tgz / EEXIST). A clean cache per build is reliable; the cost is
# re-fetching that small set of git deps. The valuable Berry cache
# (server-ce-yarn-cache) stays persistent. YARN_NETWORK_CONCURRENCY=1 is kept
# as cheap insurance against concurrent writes to the fresh cache.
#
# Preparing those git deps also makes Yarn Classic fetch esbuild's ~10
# per-platform binaries, whose downloads occasionally arrive truncated ("the
# file appears to be corrupt" / missing .yarn-tarball.tgz). Since the tmpfs is
# fresh each build there is nothing to fall back to, so we wrap the step in a
# small retry loop that wipes the classic cache and re-fetches before failing.
