/*
 * Aervo shared components. Depends on tokens.css + base.css.
 *
 * Canonical class names are listed first in every group; the remaining
 * selectors are legacy page-specific names that now resolve to the same
 * component, so existing markup (including markup built in JS) keeps working.
 * New code should use the canonical names only.
 *
 * Pages keep only LAYOUT for these classes (width, flex, margin, position);
 * look (colour, border, radius, shadow, type, padding) lives here.
