/*
 * Theme of the portal: colour tokens for light and dark, and the bridge that makes Bootstrap 5.1 use them.
 *
 * Bootstrap 5.1 only knows a light theme: its cards, tables, selects, checkboxes, dropdowns, modals and alerts carry
 * fixed light colours (and white check marks drawn as images). Every component and state the portal uses is mapped
 * here to the tokens, so a page never needs its own colours: it uses Bootstrap classes or the portal's components
 * (account.css) and works in both themes.
 *
 * The theme follows the device unless the person chose one: <html data-theme="light|dark"> (see _ThemeScript).
