自动高度 自定义高度：1920–30000px，默认 4500px 自定义高度会同步影响画布预览、任务快照、renderDocument、历史恢复和最终 PNG。若内容超过指定高度，系统会阻止导出并提示最低所需高度，不会静默裁掉底部内容。 关键修改： [PosterCreativePanel.vue (line 51)](D:/work/code/python/coding/baodanagent/frontend/src/components/poster/workspace/PosterCreativePanel.vue:51) [PosterHtmlCanvas.vue (line 1)](D:/work/code/python/coding/baodanagent/frontend/src/components/poster/long/PosterHtmlCanvas.vue:1) [poster-exporter.ts (line 95)](D:/work/code/python/coding/baodanagent/frontend/src/utils/poster-exporter.ts:95) [format_registry.py (line 17)](D:/work/code/python/coding/baodanagent/api/insurance/poster/format_registry.py:17) [render_validation.py (line 13)](D:/work/code/python/coding/baodanagent/api/insurance/poster/render_validation.py:13) 验证结果：33 项海报测试通过、Vue 类型检查通过、生产构建通过、UI 静态检查通过
