Sans is what a document is set in

Every paragraph nobody has marked is laid out in a different face from
today, on screen and on paper, so every existing document repaginates.
That is the change, not a side effect of it.

The default is now stated in one place with a name — internal/fonts'
Default — and the three restatements of it answer to that one. The PDF
exporter reads the constant rather than naming a face of its own. The
stylesheet cannot read it, being CSS, so
TestPageGeometryMatchesTheStylesheet grew four rows that compare its
font-family declarations against export.FontCSSName, which resolves a
run through styleFor rather than restating its answer: the screen's
default and the exporter's default are now the same face by test, and a
serif-marked run is serif in both.

The toolbar had 'serif' written into two expressions — the value that
means "clear the mark" and the value reported for a run that has none.
Both are fixtures/fonts.mjs's DEFAULT_FONT now, and
TestTheToolbarDefaultFontIsTheDefaultFace holds that literal, and the
order of the rendered options, to internal/fonts. This is the failure
worth naming: a toolbar that disagrees loses nothing and throws nothing,
it just labels sans text "Serif", so choosing serif appears to do
nothing and there is no error afterwards to find.

Page counts did not move: the two tests that assert them come out at 4
and 2 pages either way, measured before and after. Their thresholds
(>= 3, >= 2) are still the honest statement of what each needs — more
than one page, so there is a break to test across — so neither was
touched.

fixtures/browser-drive.mjs now drives serif rather than sans. Driving
sans would have waited for a class the control is correct never to
write, and reported the font control broken.

Intent

Attributed to this commit: 43.1 g CO₂e (5651052 tokens). This is an attribution, not a measurement — usage counted from this commit's own marker forward to the next one on worktree-sans, never backward from it. A turn that produced more than one commit books all of its tokens to the last one, and a concurrent session on this branch can add to the same figure. Some of it was priced using the shared default rate, because no model-specific factor row exists yet for at least one model involved. The Carbon view has the repo total, which is never derived from this attribution.
