1// nx_games_page.nx -- EMIT the live nishifamily.com/games portal page.
2// A sovereign games portal: classic ABSTRACT/board games built from scratch
3// (rules are not copyrightable -> clean original implementations, no ROMs
4// rehosted, no third-party code). Rung 1 ships two fully-playable in-browser
5// games: Tic-Tac-Toe (unbeatable minimax) and Connect Four (alpha-beta AI),
6// plus an honest roadmap grid. Publishing is the separate sovereign step
7// nx_aw_push (additive, vault-backed) -- the shared loop every property reuses.
8// No JS/HTML is hand-written elsewhere; this organ authors the page.
