/* Running with It — shared styles.
 *
 * Committed to one visual world rather than following the viewer's theme: the
 * app is an OLED watch app that lives on black, every screenshot is black, and
 * a light page would turn them into floating rectangles needing frames. So the
 * page is black too and the screenshots sit in it without decoration.
 *
 * Every colour below is lifted from the app itself, where they were measured
 * rather than picked — each one normalised to roughly the same perceived
 * luminance so it reads at a glance on a 162 pt screen in sunlight. Using them
 * here means the site and the thing it describes agree.
