Initial commit: private Texas Hold'em ring game site (lobby + table stub)
- 6-digit access key gate with long-lived HttpOnly cookie, brute-force limits - Lobby with saved player name and live table list - Table creation (name, starting stack, blinds, blind timer) - Table play screen stub (seats, button/SB/BB, phase, blinds, timer) - Security hardening: strict CSP, origin checks, host pinning, input sanitizing Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
