about

nx_browser_render.nx -- REUSABLE sovereign CSS render core. Holds nx_browser's OS-AGNOSTIC pipeline: br_layout (HTML body -> CSS cascade -> box/flex/float layout -> LayoutTree + computed styles) and br_draw_fb / br_shot_png (paint the laid-out page into an RGBA framebuffer / PNG). NO X11, NO network -- pure compute over sys_mmap, so it compiles into the native-Windows GUI PE exactly as into the WSL/X11 browser. The window/blit/input + fetch live in the consumers. CSS-on-native-Windows arc R2. NOTE (R3 dedup pending): these fns are still ALSO defined in runtime/_hdl_build/nx_browser.nx; once this organ is proven, nx_browser.nx imports this and drops its copies. license_tier: ORIGINAL
