     * defining their own --USER-* props in a separate file.
     *
     * The --ED-* props form the API for this styling platform. These properties
     * should remain fairly constant (though new ones may be added going forward).
     *
     * Properties with the --EDI-* naming convention are _internal_ variables that
     * shouldn't be referenced outside of this file.
     *
     * Note that the colors in this file form a dark theme. It specifically uses
     * light text (colored with --ED-text) over everything except
     * containers with a background color of --ED-surface-inv.
     * 
     * Light themes are possible by overriding these color definitions with
     * --USER-* properties in an override file.
