/*
 * ADAM — application stylesheet.
 *
 * Colour tokens for both themes followed by every component rule. Loaded by
 * both layouts: the application chrome (views/partials/layout.php) and the
 * signed-out chrome (views/partials/auth-layout.php), so the sign-in page is
 * visibly the same product as the rest of the app rather than a bare form that
 * happens to sit in front of it.
 *
 * Page-specific rules do not belong here — they live in css/pages/<page>.css
 * and are declared by the view with Asset::css().
 *
 * Theme switching: :root carries the dark palette, :root[data-theme="light"]
 * overrides it. js/theme-init.js sets the attribute before first paint.
