Gotchas

• dart fix --apply (Step 6) runs AFTER quality gates (Step 5). If it changes code, quality gates need re-running — but no re-run step exists in the workflow. Re-run them manually.
• flutter pub upgrade --major-versions upgrades all packages at once. If multiple break simultaneously, isolating the cause is very difficult. Consider upgrading high-risk packages individually.
