1// nx_andelin_v2.nx -- ANDELINWEST.COM 2.0: the team assembles the upgraded page from its own gated
2// work. Base = knowledge/andelinwest.html AFTER the team's quality loop fixed it (skip-link, nav,
3// main landmarks, search relocated to the header -- 13/13 on the NN/g+WCAG gate). This module adds
4// the visible 2.0 layer: an accessibility statement + live quality badge whose score is READ FROM
5// THE DURABLE GATE LOG (never asserted), styled, spliced before the footer, written atomically to
6// knowledge/andelinwest_v2.html -- the artifact to hot-swap onto sites/andelinwest/index.html (the
7// proven content-swap path; CONTENT is hot, no daemon restart). license_tier: ORIGINAL
