  ╔══════════════════════════════════════════════════════════════════════╗
  ║  Markdown Studio — index.html PATCH GUIDE                          ║
  ║  Apply these changes to your existing index.html                   ║
  ╚══════════════════════════════════════════════════════════════════════╝

  CHANGE 1 ── In <head>, REPLACE the existing <script src="…/vue…"> tag
              and the marked/hljs/mermaid/katex <script> tags with:
  ─────────────────────────────────────────────────────────────────────
-->

<!-- ① Vue 3 (keep as-is) -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/3.4.21/vue.global.prod.min.js"></script>

<!-- ② marked (keep as-is) -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/marked/12.0.0/marked.min.js"></script>

<!-- ③ highlight.js (keep as-is) -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/highlight.min.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/styles/github.min.css" id="hljs-theme"/>

<!-- ④ mermaid (keep as-is) -->
<script src="https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.min.js"></script>

<!-- ⑤ KaTeX (keep as-is) -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.9/dist/katex.min.css"/>
<script src="https://cdn.jsdelivr.net/npm/katex@0.16.9/dist/katex.min.js"></script>

<!-- ⑥ NEW: DOMPurify for safe HTML rendering -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/dompurify/3.1.6/purify.min.js"></script>

<!-- ⑦ NEW: CodeMirror 6 bundle — YOU provide this file.
     Place your built bundle at:  scripts/vendor/codemirror-bundle.js
     It must expose window.CM = { EditorView, EditorState, Compartment,
       keymap, lineNumbers, history, historyKeymap, defaultKeymap,
       indentOnInput, bracketMatching, closeBrackets, closeBracketsKeymap,
       syntaxHighlighting, defaultHighlightStyle, markdown, oneDark,
       undo, redo }
     Until the bundle exists the editor falls back to a plain textarea.
-->
<script src="scripts/vendor/codemirror-bundle.js" onerror="console.warn('[editor] CM bundle not found, using textarea fallback')"></script>

<!--
  CHANGE 2 ── REPLACE the old inline <script> at the bottom that mounted Vue
              with the new module-type tag:

  OLD (remove this):
    <script src="scripts/script.js"></script>

  NEW (replace with):
-->
<script type="module" src="scripts/script.js"></script>

<!--
  CHANGE 3 ── In #editor-wrap, REMOVE the <textarea id="editor-textarea" …>
              The CM6 adapter / fallback will inject itself into #editor-wrap.

  OLD (inside #editor-wrap div):
    <textarea
      id="editor-textarea"
      ref="editorRef"
      v-model="currentContent"
      :style="{whiteSpace:wordWrap?'pre-wrap':'pre',fontSize:editorFontSize+'px',lineHeight:editorLineHeight}"
      @keydown="onEditorKeydown"
      @input="onInput"
      spellcheck="false"
      placeholder="# Start writing…"
    ></textarea>

  NEW (replace with — editor.js will append CM6/textarea inside this div):
    (leave #editor-wrap div empty, or add a loading indicator)
-->
<div
  id="editor-wrap"
  v-show="activePanel==='editor'"
  @contextmenu.prevent="openEditorCtx"
  ref="editorWrap"
></div>

<!--
  CHANGE 4 ── ADD the Settings button to the topbar (after the shortcuts button).

  In the .tb-right div, after the <button class="tb-icon" @click="showShortcuts=true"> button, ADD:
-->
<button class="tb-icon" @click="openSettings" title="Settings">
  <i class="ti ti-settings"></i>
</button>

<!--
  CHANGE 5 ── ADD the Snapshot/History button to the topbar .tb-right div.
  Add after the Settings button:
-->
<button class="tb-icon" @click="openHistory" title="Version History (Ctrl+Shift+H)">
  <i class="ti ti-history"></i>
</button>

<!--
  CHANGE 6 ── ADD the autosave indicator to #statusbar (before the word count span).
  Replace the existing first <span> (Saved/Unsaved) with:
-->
<span>
  <span
    class="status-dot"
    :style="{background: autosaveStatus==='saved' ? 'var(--suc)' : autosaveStatus==='saving' ? 'var(--warn)' : 'var(--err)'}"
  ></span>
  {{ autosaveStatus === 'saved' ? 'Autosaved' : autosaveStatus === 'saving' ? 'Saving…' : 'Unsaved' }}
</span>

<!--
  CHANGE 7 ── ADD the "Save Snapshot" button in the pane-toolbar (editor side).
  Inside the <template v-if="activePanel==='editor'"> block,
  add after the last tool button group:
-->
<button class="tool-btn" @click="manualSnapshot" title="Save snapshot (version)">
  <i class="ti ti-camera"></i>
</button>

<!--
