# Pi Web (upstream main at PI_WEB_COMMIT, past its 0.12.2 tag) with the "Pi Web on Hugging Face"
# design (piweb/hf-design.patch: Claude Code Desktop's layout on Base UI: the composer with its
# "/" and "@" lists, modes and context meter; the header's panes: Changes with review comments,
# the machine's Browser (the agent also acts in the user's direct preview), Files, Terminal; the
# Hugging Face connector; Geist type, the pi mark, Lucide icons, a sidebar slot for the gateway's
# workspace menu), built from that commit and installed as its npm package would be. The patch is
# the diff of the hf-design branch in the project's pi-web-hf/ worktree against that commit
# (git diff --binary <PI_WEB_COMMIT> hf-design); nothing else is changed.
# Next runs one build worker per CPU but one (CIRCLE_NODE_TOTAL stands in for the CPU count): on
# the Space builder's 16 CPUs, 15 workers ran out of memory collecting page data (OOMKilled), so
# it builds with 4.
