nx_browser_forms_paint.nx

nx_browser_forms_paint.nx -- RENDER layer for the Nishi-browser form fields: draw a <input>/<textarea> as a bordered box with its current value + a caret when focused (password fields masked). Composes the shipped paint primitives (nx_paint_solid_rect + nx_paint_text) over the pure field state from nx_browser_forms. The browser calls this in a post-layout OVERLAY pass (one call per field, with the field's layout rect) -- decoupled from the CSS engine (which has no <input> styling). Pure framebuffer so it is pixel-gate-provable (nx_browser_forms_render_gate). license_tier: ORIGINAL
