结论：PR #273 已合并，无需审查。
“Optimize font startup for 26.1 优化字体首次加载与图集上传”当前状态为 state=closed 且 merged=true（合并时间 2026-11-13T15:30:05Z，squash 提交为 eceec46254），共 8 个文件、新增 291 行、删除 137 行。按照 AGENTS.md 的硬性规则，PR 为 closed 时立即停止、不发布任何评论，因此本轮不产出审查正文，也不改动 PR 标题。
至此，同族四条分支移植 PR 均已合并：#270（dev/1.21.4）、#271（dev/1.21.8）、#272（dev/1.21.11）、#273（dev/26.1）。如果后续有 dev/26.2 或 dev/26.3 的新 PR 处于开启状态，那才需要完整审查。
