Side B substantially improves the developer workflow by replacing the release-build fixture with a persistent `cargo watch`-based environment, adding preferred-port selection, reusable seeded data (`fixture-data/`), summary rebasing, and longer health waits, making iterative development faster and more reliable. Side A improves the CLI panel UI by grouping commands, enabling click-to-copy rows, and adding assertions to prevent unsafe JavaScript embedding, but those changes are primarily presentation and defensive checks rather than a broader workflow improvement.
