Update style

This blog was migrated to GitHub Pages without consideration. The style should be updated to take into account the type of content and align with the design language across our other products as well. The blog should have good navigation by topic, date, etc. Signing up for RSS feed, offering feedback, and finding related repositories should always be simple.

Users should see a clean interface with light animation or interaction to encourage use. It will look good across several screen sizes. If changes to front matter or additional illustrations or diagrams is required, let me know.

As part of the pull request, suggest topics that need revisiting or updating, new projects that aren't represented, or emerging themes worth talking about.

If you have questions about what direction is best, create a template switcher or demo page with 2-4 options that are different from each other but all appropriate to the task.

Start by reviewing the blog's current SCSS and page structure to understand the existing design and content organization. Define a focused design direction before changing the interface; done should include clear topic/date navigation, simple RSS, feedback and repository discovery, responsive layouts, and light interaction across screen sizes.
