 * Two render contracts driven by the markup:

 *      first paint, JS only wires the click→smooth-scroll handler.
 *
 *   2. Scroll-past gated (data-observe-target=".some-selector") — shop
 *      PDPs. Hidden from first paint via the [data-observe-target]
 *      attribute selector below. JS adds .is-revealed once the inline
 *      target has scrolled above the viewport.
 *
 * The attribute selector is what eliminates FOUC on PDP — the button is
 * already in its correct (hidden) state at first paint, before any JS
 * runs. Footer-loaded scripts can't compete with first-paint timing
 * otherwise.
