tests/layout/baseline.json records where each page starts and what the load cost, per
engine and platform; a page starting elsewhere is a layout change the run prints page by
page, a load over three times its recorded time a regression, and LAYOUT_UPDATE=1 records
it again. The monkey draws frame sizes, wraps, alignment and column counts too, holds the
history against the edits rather than the caches the editor recomputes, and leaves it
unchecked where the columns flow rewrote the document outside it. The differences both
importers make by design are named in the comparison; unhoist moved to normalize.ts.
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.
