// brand.md — "download this brand" from the report's own menu.
//
// One markdown page distilled from the capture: name, palette with the hexes,
// the type that was actually declared, the logos, the handles that were
// verified, and the voice read off the brand's own copy. Built by the same
// pure renderer the panel uses, so the file is the same file.
