/**
 * SnapPlugin – adds snap-to-nearest behaviour to ScrollToSmooth.
 *
 * After the user stops scrolling the page automatically animates to the
 * nearest anchor / snap target.  Import and register once before creating
 * any ScrollToSmooth instances:
 *
 *   import { ScrollToSmooth } from 'scrolltosmooth';
 *   import { SnapPlugin } from 'scrolltosmooth/plugins/snap';
 *
 *   ScrollToSmooth.use(SnapPlugin);
 *
 * Options added by this plugin:
 *   snap          – enable snapping (true / 'nearest')
 *   snapSelector  – CSS selector for snap targets (falls back to link targets)
 *   snapDebounce  – ms of inactivity before snapping fires (default 150)
