/* Farmacin CZ — food supplement landing
 *
 * Direction: cyanotype. Anna Atkins printed botanical specimens as white
 * silhouettes on Prussian blue in the 1840s — the first photographic book was
 * a herbarium. The product is nine plants and a vitamin, and its packaging is
 * already deep blue, so the reference is not decoration: the composition IS
 * the subject, and the herbarium sheet is where the page spends its boldness.
 *
 * Monochrome on purpose. No second accent colour — cyanotype has none.
 * All pairs verified against WCAG AA before use.
