/* =========================================================================
 * DriftSense -- help-tip system
 *
 * Usage in HTML:
 *
 *   <span class="ds-help"
 *         data-help-title="Change-frequency ranking"
 *         data-help-body="Top 20 files by change count over the last 30
 *                         days. Files that show up here are churny
 *                         'live-config' files. Pin them to a Named
 *                         Release to freeze their current-latest content."
 *         data-help-link="/pin_hotspots.cgi"
 *         data-help-link-label="Try bulk pinning &rarr;">
 *   </span>
 *
 * The <span> renders as a small teal "?" chip. On hover / focus, a
 * gorgeous dark popover fades in above the chip with title + body +
 * optional link. Pure CSS + tiny JS in ds_help.js.
