Some style-related changes

[obfuscated-loop]

Changes:

• Improved the box-shadow for the .shadow class that is used (https://getcssscan.com/css-box-shadow-examples)
• Added a comma delimiter for the post categories - as range is used to loop through the categories, you can't easily use Hugo's delimit function; I used a CSS rule.
• Removed the unused author name from articles as it added an extra '|' character before the date previously + same functionality for articles without categories
• Made it so the related posts block only shows if their are related posts to show to begin with
• Rounded the thumbnail images for featured articles
• Made article titles bold - I think it improves the UI
• Converted SVG search icon to FontAwesome

Here's a preview I've attached below:

I was also watching your recent stream on Cursor (https://www.youtube.com/watch?v=8h6Kpac5U2c) and heard you were thinking of doing an overhaul on the site - that's initially why I decided to clone the repo and take a look. I will happily help out with this if you'd like.

Have a good one.
