/*
 * Code blocks of the research site: the editor frame around code coloured at build time (highlighter.mjs).
 *
 * Ground and token colours are the docs code theme oraclizer-dark (Web/Docs/src/lib/highlight.ts): the night
 * ground (--codeblock-bg, #0b111b on light pages, #05080d on dark pages) and the theme's token colours,
 * written inline by the build. The frame follows the docs code block (hairline border, mono header with the
 * language, outlined Copy button) and adds the editor parts: line numbers that stay put while the code
 * scrolls sideways, the row under the pointer lit, marked rows, a visible keyboard focus.
 *
 * The block is dark on both page themes. Load after research.css and features/site/theme.css.
 * Markup (from highlighter.mjs renderBlock, or built by code.js around an older block):
 *   <div class="orz-code code-block" data-lang data-kind="code|plain" [data-numbers] [data-highlight]>
 *     <div class="orz-code__bar" data-orz-ui> language, file name, Copy button </div>
 *     <pre class="shiki" tabindex="0"><code><span class="line">...</span>\n...</code></pre>
 *   </div>
