/* Shared, NON-isolated styling for code blocks.
   Two consumers render deliberately identical looks:
     1. CodeBlockComp        -> .tng-code-block*  (Blazor component markup)
     2. TngCodeBlockRenderer -> .markdown-code*   (raw HTML from Markdig)
   Scoped .razor.css can never reach the HTML Markdig emits, which previously
   forced a full copy of these rules into MarkdownContent.css - and the copy
   silently lost two dark-theme overrides (language label and gutter turned
   invisible). Grouping both markups on one rule set keeps them in sync by
   construction. */
