/* Mermaid v11 attaches helper elements directly to <body> outside React's tree:
   1) A transient <div id="dmermaid-…"> render scratchpad (~150px tall, lives
      ~500ms during render) used for layout measurement.
   2) A persistent <div class="mermaidTooltip"> shared across renders.
   Both default to position:absolute with no top/left, so they land in body's
   normal flow below <main h-screen> and inflate documentElement.scrollHeight,
   producing a page-level scrollbar that flashes during render and persists
   afterwards across Tab switches. Force fixed so they don't contribute to
   page scroll dimensions. */
