"""Generate the Furtka brand files from the winning logo (Mark M) everywhere
it ships: website, live installer, on-box UI, ISO boot splash, repo docs.

    python3 website/tools/brand-assets.py

Reuses the geometry and rasteriser of logo-assets.py (the poll showcase), so
the mark is drawn from one source. Needs the same build-only deps: cairosvg,
Pillow, fontTools. Output files are committed; re-run after a geometry change.
