* add keywords and article tags for seo
* replace youtube embed with lite-youtube component for faster page loads
* use youtube regex to add proper id check to render youtube component
* add dynamic imports for faster builds and improving page speed performance
* remove podcast embed iframe and replace with link due to slower page loads
* Move all markdown into a dedicated `content/` directory
* use contentlayer (https://github.com/contentlayerdev/contentlayer) for loading markdown
* add catch all route pages/[...slug].js to generate all markdown routes using contentlayer to find pages
