/*
 * @sigmashake/design-tokens - app shell and component layer.
 *
 * Use this file with tokens.css. Load tokens.css first.
 * Every value comes from a var(--ss-*) token. This file has no raw color.
 * Every class starts with ss-. Plain CSS. No framework. No font file.
 *
 * Layout:  ss-app = search bar over (rail | sidebar | main | detail).
 * Theme:   dark is the default. Set data-theme="light", "contrast" or "dark" on a parent.
 *          The setting of the operating system does not change the theme.
 * Density: set data-density="compact" on a parent.
 * Detail:  set data-detail="open" on ss-app to show the detail pane.
 * Drawer:  below 768px the rail and sidebar leave the page.
 *          Set data-drawer="open" on ss-app to show them.
 *
 * Red is the mark. Use it for fills, badges, unread and selected marks, and the focus ring.
 * Do not use red for text. Text on a red fill is black.
 * Use ss-app for app and console products. Marketing and content products use the
 * tokens and the controls only. Overlays and games do not use this file.
