/*
 * The shared look of edrys-Lite modules, in the theme of the classroom.
 *
 * Load it after water.css:
 *   <link rel="stylesheet" href="https://edrys-labs.github.io/module/vendor/water.min.css" />
 *   <link rel="stylesheet" href="https://edrys-labs.github.io/module/edrys-module.css" />
 *   <script src="https://edrys-labs.github.io/module/edrys.js"></script>
 *
 * edrys.js puts the classroom's theme on <html data-theme="light|dark">.
 * Without it (the page opened on its own) the system setting decides. The
 * --edrys-* variables are there for modules without water.css, and for
 * editors and terminals that take colors in JavaScript
 * (getComputedStyle(document.documentElement).getPropertyValue('--edrys-bg')).
 *
 * Parts for the module layout (no title inside the module, the frame shows
 * its name): .edrys-toolbar (status pill left, secondary actions right),
 * .edrys-footer (main actions), .edrys-pill (.ok, .warn, .error),
 * button.primary, .edrys-terminal.
