doc-view

sparkles:doc-view is the document viewer hue grew, as a library: load a file as a document — source code, markdown, a DSV table, a diff, a twoslash payload — and view it with hue's views, wrapping, folding, search and scroll anchoring. hue mounts it as its document pane; sparkles:terminal opens the files its programs ask for in it (UIA14, TDV).

It has two halves, gated on what the consumer links rather than on a configuration of its own:

• The model — DocumentPipeline (read → detect → highlight → parse) and ViewerModel (the laid-out widget tree, its display list, folds, search, the scroll anchor). Raylib-free; it builds wherever hue's terminal build does.
• The pane — DocViewPane, the model plus keys and a GPU painter, for any sparkles:ui-raylib window. It compiles where the consumer depends on sparkles:ui-raylib; the off-screen-VT decoder for ```ansi fences where it depends on sparkles:ghostty.

The library makes no network requests and runs nothing a document names: a URL is fetched only through a host's DocumentPipeline.fetchUrl, and markdown includes stay inside the document's tree (VIW7).
