The template harness, tests and thumbnails now use a neutral vendor, bank account and
a generated sample wordmark (scripts/logo/make-sample-logo.mjs). Layout goldens and the
14 picker thumbnails are regenerated. Fixture strings keep their original lengths where
layout tests depend on them.
Marble uses a flat-to-gradient band in place of the marble photo and bundles Lustria (OFL).
Both logo slots are opt-in. Quirk 13 documents a fontkit glyph-cache issue that the
tests work around with warm-up renders; the engine fix follows separately.
