/* Caffè Rosso — "Il Manuale"
 *
 * The content is a manual: brewing procedures and equipment specifications.
 * So the page is set like one. Headings are display type, running text is a
 * proper reading serif, and every measured value — wattage, capacity, weight,
 * ratio — is set in mono so the numbers line up and read as data.
 *
 * The buying guides carry a numbered product list whose specifications were
 * already in the copy as loose one-line paragraphs. They are regrouped into
 * spec cards (see tools/wpstatic/products.py); the wording is untouched.
 *
 * The palette is from the name. "Rosso" is the one distinctive asset this
 * brand has, and no competitor uses it; brown would disappear.
 */

/* ------------------------------------------------------------------ font -- */

/* Archivo for headings: a dense grotesque with the flat, slightly compressed
 * look of Italian signage and technical labelling, and enough weight to hold
 * its own against the red. Source Serif 4 for running text: drawn for long
 * reading on screen, with a large x-height that survives at 1.19rem. Plex
 * Mono for every measured value, so figures align in the spec tables. */
