Module template 

Template expression evaluator.

Takes a template JSON tree (with $ref, $each, $if, operators) and a data JSON object, resolves all expressions, and produces a plain document JSON tree that can be deserialized into a Document and rendered.

This enables a hosted API workflow: store template JSON + dynamic data → produce PDFs without a JavaScript runtime.

Structs

EvalContext

Evaluation context that holds data and scoped bindings (from $each).

Functions

evaluate_template

Evaluate a template JSON tree with data, producing a resolved document.
