- use `document.importNode` to create a clone of post card elements when pulling them in from infinite scroll pages
- cloning the element means the element's owner document matches the viewed document and ensures images in the inserted post card elements are sized according to the viewed document
no issue
- replaces author hover JS that was lost during merge
- replaces `floating-header.js` with `sticky-nav-title.js` containing the relevant JS that was lost during merge with a cleanup for unused variables and unnecessary event listeners
- removes reference to non-existent `{{> floating-header}}` partial
no issue

- gallery card support
- use `gulp-concat` to concatenate all JS files into a single `built/casper.js` file
- reduces external JS file requests from 3 (jquery, infinite-scroll.js, jquery.fitvids.js) down to 2 (jquery, casper.js) and reduces page size by removing repeated inline code
