/**
 * Code Block Styling for vinceverbon.com
 * Module: vv_code_blocks (theme-update-proof)
 *
 * Works with Prism.js (Tomorrow Night theme loaded via CDN).
 * CKEditor 5 outputs: <pre><code class="language-xxx">
 *
 * AI COWRITING NOTE:
 * When writing articles with code blocks, use the CKEditor "Code Block"
 * button and select the appropriate language. The frontend will automatically:
 *   - Apply syntax highlighting (via Prism.js)
 *   - Show a language label (top-right)
 *   - Show a copy button (top-right, next to label)
 *
 * Supported languages in CKEditor:
 *   plaintext, c, cs (C#), cpp (C++), css, diff, html, java, javascript,
 *   php, python, ruby, typescript, xml, bash, yaml, json, prompt (AI Prompt)
