Overview

Content-stream layer. Pages and Form XObjects carry a content stream: a sequence of operands operator instructions that draw graphics and text. This layer parses, walks, and emits those streams.

Architecture mirrors HexaPDF::Content:

* +Tokenizer+ from Source layer produces tokens (content
streams use the same PDF object syntax as COS values).
* +Content::Parser+ groups operands + operator into invocations.
* +Content::Operator::Base+ subclasses implement each PDF
operator (one file per category — open/closed via `register`).
* +Content::Processor+ walks a stream, invoking operators
against a +GraphicsState+ (with a stack for `q`/`Q`).
* +Content::Canvas+ is the high-level drawing API on a Stream.
