openApp() passes page options through, so the showcase run sets
deviceScaleFactor 2 — same CSS viewport and layout as the tests, 2800x2000 px
images that stay sharp where the README scales them down.
Header and footer go first, each with its own ops, and a variant flag is
flipped while a zone is open. The round trip compares a list's drawn kind and
marker rather than its node type and style name — a list that loses its name to
a formatted marker carries the style's own char — and skips the marks of an
inline atom, which no file keeps. A caret is snapped to a text position, a
swallowed File-menu click is retried, and WebKit's converging ResizeObserver
round is no page error. A new corpus pair brings all six zones through the
import path; the baseline holds it and a re-recorded showcase entry.
lo-fuzz.test.ts hands every fuzz seed to LibreOffice as .odt and .docx and
compares what comes back, listing the differences LibreOffice makes by design.
test:layout opens the corpus, the showcase and fuzz seeds in the browser, holds
the page count against LibreOffice and checks the lines for overlap, margin
escapes and stranded headings. test:monkey types at random on corpus documents
and asserts the schema, undo to the start, redo, and that both saved formats
read back. browser.mjs now carries the dev server and the settle helper.
openApp() launches chromium, firefox or webkit from playwright-core; the smoke
and DOM runs pass in each. CI runs both per engine, WebKit on macOS for
Safari's text shaping. build.target is set explicitly to the browsers the
bundle promises. CLAUDE.md is back under its 120-line budget.
npm run test:dom opens a corpus document in headless Chromium and holds
its page count against a settle, a reload, a zoom, a page break and its
undo, plus the unsaved dot — the components the vitest suite cannot see.
The smoke run now shares its boot with it (tests/browser.mjs).
