Auto-Update Cart on Quantity Change
Removes the 'Update cart' button and automatically submits the WooCommerce cart form whenever a quantity input value changes.
Lazy YouTube Facade Click-to-Load
Replaces YouTube embeds with a lightweight thumbnail facade and play button; the actual iframe is only inserted after the user clicks, deferring the heavy YouTube scripts.

Read More / Read Less Toggle
Collapses long text blocks to a configurable height and adds a Read More / Read Less button that smoothly expands and collapses the content.

Copies the current page URL to the clipboard when any element with a data-copy-url attribute is clicked, with a brief visual confirmation.
Image Magnifier Zoom on Hover

Cycles through a pipe-separated list of phrases on any element with a data-typewriter attribute, typing and deleting each phrase in turn.
Animated Number Counter on Scroll
Counts up numeric values inside elements with a data-counter attribute when they enter the viewport, using an eased animation for a polished statistics section.
Scrollspy Active Navigation Highlight
