/* The half of the light/dark image switch that Material does not ship.
 *
 * Material's own stylesheet carries exactly two selectors for this:
 *
 *   [data-md-color-scheme=default] img[src$="#only-dark"],
 *   [data-md-color-scheme=default] img[src$="#gh-dark-mode-only"] { display: none }
 *
 * Both hide the *dark* variant in the *light* scheme. Nothing hides the light
 * variant in the slate scheme, so a page offering both -- as the landing page's
 * hero does -- renders them stacked once the reader switches to dark. This is
 * the mirror rule.
