/*
 * catalog.css - redesigned /catalog index (visual reference: image 3 of the redesign brief).
 *
 * Loaded from src/application/view/catalog/view_catalog_index.php only, so it never reaches another page.
 * Every selector is scoped to .cat-index (checked by an automated test): it cannot restyle the homepage, the global
 * navigation, the footer, the category pages or the product pages. No JavaScript, no external requests.
 * Font: Montserrat, already loaded by the site's header.php.
 *
 * The legacy stylesheets (bootstrap.css, main.css) are loaded before this file and set uppercase green Oswald headings,
 * 45px margins on p/ul/h*, and a grey .breadcrumb. The resets below are therefore explicit.
