1.7Baseline Management

Strategy	How It Works	Pros	Cons
Git-tracked baselines	Store baseline PNGs in the repo	Versioned with code, simple	Repo bloat, merge conflicts
Cloud storage	Store in S3/GCS, reference by hash	No repo bloat, unlimited storage	Extra infra to manage
Tool-managed	Percy/Chromatic manage baselines	Zero maintenance, auto-approval UI	Vendor lock-in, cost
Branch-based	Baseline = screenshots from main branch	Always comparing against production	Cold start for new pages

The cloud storage approach with tool-managed approval workflows (Percy, Chromatic) provides the best developer experience. Git-tracked baselines work well for smaller projects.

Pro Tip: AI-powered visual comparison is not a silver bullet -- it introduces non-determinism and cost. But for teams drowning in false positives from pixel-diff tools, it transforms visual regression testing from a burden into a useful safety net.
