Could you build this?

Partial While the Phlex DSL syntax wrapper is standard Ruby, building a pure-Ruby PDF rendering engine from scratch with TrueType font parsing, cross-reference tables, and box layout algorithms is a major systems undertaking.

What it would actually take: A ground-up PDF generation engine without dependencies like Prawn requires parsing TrueType/OpenType binary tables (glyf, cmap, hmtx) for font embedding/subsetting, implementing a CSS-like box-model layout and page-breaking algorithm, and generating valid low-level PDF byte streams (objects, xref tables, and compression streams). This requires deep expertise in binary specifications and layout layout engine design.
