Seed via API, Verify in UI (Playwright + TypeScript, Ch.16)

This is the payoff of everything so far. A UI test usually cares about one

behavior — does this article render? — but reaching that state through the UI means

logging in, opening the editor, filling four fields, and publishing, every single

time. That's slow and, worse, it makes the test fail for reasons unrelated to what

it's checking.

The integration pattern fixes it: do setup through the API, verify through the

UI. We already have the pieces — makeArticle (Chapter 14) creates data in

milliseconds; now we just point the browser at it.

Code for this chapter is tagged ch-16 in the repo:



and tell me how much of your UI setup you've moved to the API.
