# `Pdf.Reader.Outline`
[🔗](https://github.com/MisaelMa/ExPDF/blob/v1.0.1/lib/pdf/reader/outline.ex#L1)

Represents a single node in a PDF document outline (bookmark tree).

The outline tree is a linked-list structure where each node may have
sibling nodes (via `/Next`) and child nodes (via `/First`). This struct
captures the resolved, tree-shaped representation after the walker has
followed those links.
