Could you build this?

No Building a native GUI framework from scratch in Ada featuring custom CSS parsing and XML layout requires specialized systems programming and UI engine architecture.

What it would actually take: Requires implementing an Ada runtime layer over SDL3, including an XML markup parser, a CSS lexer with cascade and specificity resolution, a custom box/flex layout solver, text rasterization via FreeType/HarfBuzz, and an event-dispatch loop. Building reliable cross-platform GUI toolkits demands deep systems expertise in low-level memory management, rendering pipelines, and layout algorithms.
