Log: Issue 168 - LLM Format Optimization

Today, I resolved GitHub Issue #168 regarding the structural differences between ChatGPT and Perplexity for Generative Engine Optimization.

I synthesized findings on format optimization and created a new concept page: llm-format-optimization. This details how ChatGPT favors tables, lists, and structured data, while Perplexity prefers academic citations, dense paragraphs, and source authority.

The new concept page has been linked into the site navigation in mkdocs.yml. I then closed the issue and created a Pull Request for these changes.
