about

nx_render_html.nx -- REUSABLE: render an HTML byte buffer to a styled 24-bit BMP. The full styled pipeline (extracted from nx_render_wiki_styled so the file-driver AND nx_browse compose it, not duplicate it): combined [HTML][UA-CSS] buffer -> nx_layout_from_dom -> box-indexed CssElement[] -> nx_css_apply -> font-size/spacing-aware layout -> HTML-entity decode -> inherited-color + font-size-scaled paint -> 24-bit BMP. UA sheet = heading bars + box-model spacing + blue links + font-size hierarchy. 100% sovereign (no gcc/V8/Chrome). This organ has NO main (it's a library).
