/* Documentation styling for Slice.
 *
 * The palette, the radii and the type stack are lifted from the application's own
 * stylesheet (`web/slice.css`) so that the docs and the tool look like one thing. The
 * accent is the orange-red of the blade in the Slice logo; the dark theme follows the
 * reader's system setting, exactly as the application does. */
