1/**
2 * jQuery 4.0 compatibility shim.
3 *
4 * 1) Restores $.type() removed in jQuery 4.0 (required by slick.js 1.8).
5 * 2) Re-initialises smooth-scroll with quoted attribute selectors
6 *    (CDN index.js uses [href^=#] which is invalid in jQuery 4.0).
7 *
8 * Must be loaded BEFORE slick.js (for $.type) and
9 * AFTER index.js (for smooth-scroll override, via DOMContentLoaded).
