What and why

A revised draft's review shows what Tin changed above the article. The note was a paragraph between the version row and the copy, up to 2,000 characters of it, so the founder read notes before the page they came to review.

The note now folds into the version row, as picked on the Paper board "Review · what changed, folded" (WC-A):

• Closed: "What changed" with a down chevron joins Version, Previous version and Compare. Nothing else shows above the article.
• Open: the item turns to the ink, the chevron points up, and the whole note eases in under the row. Height and opacity move together over about a quarter of a second, with no motion under reduced motion.
• It stays open across redraws of the same review, and works the same in Decisions and the reader, which share the component.
• The review returns the whole note, as before.
• The revision prompt now asks What changed to start with one sentence of at most 25 words that a reader takes in at a glance, with any detail after it in the same section.

An earlier version of this PR cut the note to its first sentence on the server. That's gone: folding keeps the whole note one click away.

Verification

• node --test web/workflow-review.browser.test.js: 7 passed. The article feedback test now checks that What changed starts closed with a zero-height fold, opens on click with aria-expanded="true", and shows the note.
• uv run pytest tests/test_workflow_reviews.py against a local Postgres, plus ruff check.
• Rendered the Aupilot demo's revised article in the packaged dashboard, closed and open: it matches the WC-A board.

Tested on staging

See the comment below for the staging run. Staging has no revised draft yet, so the fold itself was checked with the browser test and the render above.

Tested on staging (run 41733225552, with main, #524 at 9226457 and #537): app.staging.tin.computer serves the fold (.review-change-fold in workflow-review.css, review-change-toggle in workflow-review.js). Staging has no revised draft to open, so the fold's behaviour is covered by the browser test and the Aupilot render in the description.
