/*
 * The Theme Kit in Cargo's look. The kit (themes/_shared/assets/css/kit.css) draws every block the theme has no
 * template for, and every module section; this file sets its tokens and the look of its parts, linked after kit.css, so
 * the values here win. The theme's marks on whole sections (the route over a heading, steps and milestones as stops on a
 * route, the ribs of a dark band) are in theme.css, which knows each block's type.
 *
 * The look: firm and plain, like a shipping label. Small corners, headings in large condensed letters in sentence case,
 * small labels in spaced capitals, cards that are labels (white, a fine edge and a heavy rule across the top), and one
 * signal colour, the accent, for every button and every mark: the main colour is kept for the header, the dark bands
 * and the footer.
 *
 * Rules for this file: it loads nothing, no picture, font or address of any kind (the kit inlines it into module
 * previews; kit_components.test.php fails for one, and also for these words written in a comment);
 * colours only through the palette tokens the kit already reads (--text-primary, --surface, --primary, ...) or
 * color-mix() of them; weights only through the layout's --cargo-heading-weight and --cargo-body-strong.
 *
 * --kit-radius and --kit-button-radius are repeated in this theme's line of the shared button table
 * (themes/_shared/assets/css/resilience.css, --chrome-radius and --chrome-button-radius) so the cookie notice and the
 * phone action bar match the theme's own cards and buttons: theme-chrome.test.mjs compares the two. Change both.
