Meridian: A peer-to-peer browser game world built by an AI agent

Meridian now runs as a playable demo from GitHub Pages on desktop or phone, with touch controls, a first-minute tour, and solo play by default since the temporary public lighthouse is switched off. The post details renderer polish (WebGL2 ray pass with CPU fallback, filmic tone mapping, sight- and focus-scaled rays), a minimap that paints where the view meets the ground, new agility and perception skills, and AI players driven only through the same keys a person presses. It also lists merged batches after recording: positional sound and hearing skills, trampled paths, 25 cm terrain cells, a leaner wire format (79% fewer bytes in one capture), a phone blank-screen fix, and a scaling bench run only to 4 clients.
