* add npm dependencies used in this theme

* implement helper to configure JS and ESBuild

* migrate jquery popper.js bootstrap fontawesome to js bundle

* move ityped to js asset, implement experiences horizontal vertical line in css

* align recent post height via css

* migrated home.js and refactored into various sections

* migrated darkMode feature to js bundle

* moved mermaid feature to js bundle

* migrate syntax highlight to js bundle

* migrate katex ( js portion ) to js bundle

* migrate pdf-js to js bundle by delegating to cdn

* set explicit comparisions for feature envvars so js can properly optimize

* removed goat-counter

* more fixes for broken achievements and small bugs

* more bug fixes

* allow configuration of hightlight.js, fix video-player shortcode

* remove jquery all together

* add null handling and fix merge conflicts
