Pretext

Type: text-measurement primitive

Pretext is the measurement and layout primitive in the candidate stack.

Why it matters

• clean split between one-time text preparation and hot-path layout
• strong proof that measurement can be derived without DOM reflow
• useful for future large-doc and page-layout work

Strongest local evidence

• ../pretext/README.md

Limits

• not a direct answer to annotation/comment ownership
• important for layout, not for legacy decorate replacement on its own
