/**
 * Page object for the Code-node editor surface.
 *
 * Cohesive cluster spanning three render targets:
 *   - in-NDV roots: the Code / Ask-AI tabs (`code-node-tab-code`,
 *     `code-node-tab-ai`), the Ask-AI CTA + prompt, the
 *     `code-editor-fullscreen-button` and the in-NDV CodeMirror editor for the
 *     `jsCode` parameter
 *   - teleported overlays resolved through the derived `Page`: Ask-AI CTA
 *     tooltips (`ask-ai-cta-tooltip-*`) and the CodeMirror lint tooltip
 *     (`.cm-tooltip-lint`)
 *   - teleported fullscreen code editor (`code-editor-fullscreen`). Its hosting
 *     `.el-dialog` shell is owned by `BaseModal` / `dialogLocators`; this
 *     component scopes only to its own teleport root.
 *
 * @example
 * // Inside a hosting page object
 * readonly codeNodeEditor = new CodeNodeEditor(this.container);
 *
 * // Inside a test
 * await n8n.ndv.clickAskAiTab();
 * await n8n.ndv.getAskAiPromptInput().fill('Some prompt');
