Multiline text measurement and line breaking without DOM layout (Pretext / @chenglou/pretext).

Also use when the user says Pretext, 文本测量, 无 DOM 换行高度, or line-break layout in TypeScript.

Use when asked to plan out, break down, or organize a multi-step project, research task, or any work requiring >5 tool calls. Supports automatic session recovery after /clear.
