Could you build this?
No Developing a custom native macOS Markdown layout and rendering engine requires specialized expertise in low-level platform typography and text layout frameworks like TextKit 2 and CoreText.
What it would actually take: Requires native Swift/Objective-C development interfacing directly with Apple's TextKit 2, CoreText, and AppKit/CoreGraphics rendering pipelines. The hard part is building an efficient AST-to-text layout engine supporting custom line fragments, nested block layouts, interactive inline elements, and syntax-highlighted code blocks at 60fps without layout thrashing. Deep systems-level knowledge of macOS text architecture is required.
