/* || COLORS
 *
 * The watterblock uses the following color system:
 *
 * 1. At the top, there are themes. The entire app always uses the same theme.
 *    Currently, there is one dark and one light theme, defaulting to dark.
 * 2. Each theme contains two color sets, "regular" and "alternate". Individual
 *    components always use the same set, but their parent or child components
 *    may differ. Color sets within a theme are meant to complement each other.
 * 3. Each color set contains three main colors: text, background and accent.
 * 4. Each color set also contains additional colors derived from the main
 *    three. For the moment these need to be calculated at authoring time, but
 *    the intention is to use relative colors once they are baseline widely
 *    available, which should happen around April 2027.
 * 5. The "current" color set redefines the applicable colors based on which
 *    color set is currently active. Components are meant to rely on it.
