Repro: on main (no local changes) npx playwright test builder-p1-site builder-p2-dynamic-post --workers=2 failed 1 of 3 runs; different victim spec each time (p1-site, p2-dynamic, p2-interactive, p3-featured, f3-undo). All these specs insert blocks into the SAME target post (default postId 9 via loginToBuilder) and assert with 5s timeouts -> parallel workers race on one document.
Fix direction: dedicated fixture post per spec family (pattern established with perf fixture post 15 in #25), or per-run doc reset via REST in beforeEach. Until then, expect ~1 flake/full-suite-run at workers=2; workers=1 is stable.
