Mixed Lab v2

Multiplies final wall alpha. 1.0 = solid (default), 0.0 = invisible. Drop to ~0.5 to see through walls while inspecting interior pattern math.

Auto-saves to localStorage on every change ; survives reload.

Opens last_ship_sailing_v8VR.html and surfaces the baked-in const DEFAULT_WALL_CONFIG = {...} block. Edit the JSON in the textarea below, then save back. The lab's multi-layer bg/fg/fg2 shader is a different schema than the game's flat single-layer wallParams; sync here is the raw JSON for the game's seed config. Uses File System Access (Chrome / Edge) for direct writes; other browsers fall back to a download.
