Runs the two-arm load gate on the dev arm at CI budgets against a real 3,000-clip project generated at run time, plus the eager bundle byte check on every studio PR. The bundle check enforces a ratchet at 870,000B rather than the 600KiB target. The target needs a Node-only AST/DOM stack out of the browser bundle, which is its own unit; enforcing it now would mean a permanently red check, and a permanently red check gets muted. The ratchet cannot be regressed past and every run reports the remaining gap.
