/* charts.css - styles for assets/js/charts.js.
 *
 * Shared by the admin dashboard and the customer account page, which have
 * separate palettes: admin.css names its colours --accent and --border and
 * swaps them for dark mode, forms.css names them --blue and --line and has
 * no dark mode at all.
 *
 * Rather than keep two copies of these rules, each colour is written as
 * var(--accent, var(--gf-blue)): the admin variable if it exists, and the
 * shared token from tokens.css otherwise. Admin keeps its theme switching,
 * the customer side gets the right light colours, and there is one file.
 *
 * Load tokens.css before this.
