eyp viewer

The eyp viewer renders and validates EYP documents from a source input, delivering a clear, testable representation of content structure for developers, data engineers, and technical writers. It enables quick verification of syntax and hierarchical relationships without requiring a full execution environment.
Core logic includes a YAML-like parser for EYP, includes resolution, and a renderer that produces an HTML-like preview or a structured data payload. Required inputs are eyp_source and render_mode; optional features include theme, max_width, and annotation controls to aid debugging.
Outputs include rendered_html, a metrics object with render_time_ms and warnings, and an errors array for invalid inputs. The tool supports multiple locales, defaulting to en-us, and uses pixel units for layout hints when present. It is designed to help teams compare, validate, and accelerate content workflows.
