+   ============================================================================
+   Both the editor (PM decorations, `code-block-shiki.tsx`) and the publisher
+   (static HTML, `transformers/highlight-code.ts`) emit the same markup:
+
+     <pre class="shiki ..." data-lang="python"
+          style="--shiki-light:...;--shiki-dark:...">
+       <code class="language-python">
+         <span class="code-line-num">1</span>
+         <span style="--shiki-light:#d73a49">const</span> foo = ...
+         <span class="code-line-num">2</span>
+         ...
+       </code>
+     </pre>
+
+   - Shiki is configured with `defaultColor: false`, so tokens carry BOTH
+     theme colors as CSS vars. We pick the active var based on
+     `html[data-theme=...]` for zero-JS live theme switching.
+   - Line numbers are physical markup (`<span class="code-line-num">`) rather
+     than CSS counters. In the editor PM widget decorations inject them; in
+     the published HTML the highlight-code transformer does the same. Placing
+     them as the first child of each line means they sit on the first visual
+     row of soft-wrapped lines automatically - no absolute positioning math.
+   - The language label comes from a `::after` pseudo on `<pre>` using
+     `attr(data-lang)`, so no extra DOM node exists. */
