Website & rebrand to Signal Decay

Built the landing page. Dark, atmospheric, text-forward. The page itself should feel like opening a terminal log from Khael-Vorath.

Added a full story page with all 14 chapters of the game's narrative, a devlog (you're here), skill tooltips on class cards with real game data, and a zone showcase that doesn't spoil discovery.

Renamed from "Land of Nomads" to "Signal Decay." The signal was always the point.
