 本轮补充：renderer/snapshot 增加 opt-in DEC 2026 synchronized output 包裹入口，可用官方 BSU/ESU (`CSI ?2026h`/`CSI ?2026l`) 生成整帧 ANSI fixture，同时默认渲染保持不变。
 
 本轮补充：terminal OSC helper 增加 OSC 0 title/icon 序列生成，输入会先 strip ANSI；`StripANSI` 现在会完整跳过 OSC/DCS/APC/PM/SOS payload，避免 title/snapshot 可见文本被终端控制串污染。

 - `internal/tui`: terminal CSI parsing now distinguishes parameterized `CSI Pl;Pr s` left/right horizontal margin regions from bare `CSI s` save-cursor semantics.
 - `internal/tui`: terminal CSI parsing now recognizes intermediate-space `CSI Ps SP @` / `CSI Ps SP A` scroll-left/right sequences instead of misclassifying them as insert-characters or cursor-up.
 - `internal/tui`: terminal ESC parsing now exposes DEC line/screen attribute controls (`ESC # 3/4/5/6/8`) as structured screen actions instead of falling back to unknown.
+- `internal/tui`: terminal ESC parsing now maps DECID identify-terminal (`ESC Z`) to the existing device-attributes report action, matching the `CSI c` query path.
 - `internal/tui`: terminal CSI parsing now marks DEC selective erase `CSI ? Ps J` / `CSI ? Ps K` separately from ordinary ED/EL erase actions.
 - `internal/tui`: terminal CSI parsing now exposes ECMA `CSI Ps N` / `CSI Ps O` erase-in-field and erase-in-area actions with the same to-end/to-start/all regions used by other erase operations.
 - `internal/tui`: terminal CSI parsing now treats explicit zero count/position params as ANSI defaults for cursor movement/position/column, insert/repeat/erase chars, and scroll actions while preserving raw zero selector semantics for mode/report/erase selector sequences.
