about

nx_wasm_physlab.nx -- PHYSLAB: the VISIBLE consumer of the shared 3D core (reuse census W2: "a game surface consumes nx_phys3d + nx_softjiggle"). Crates STACK and fall ASLEEP (dimmed = sleeping, visibly), spheres BOUNCE with real restitution, and a 5-node JIGGLE CHAIN hangs from the mouse and swings AROUND a capsule pillar (collision visible). Click spawns crates. ALL game logic lives here (the no-JS-logic law): JS may only pass raw mouse state and blit the framebuffer. ALL INTEGER (phys3d/softjiggle fixed-point law) -- the ENTIRE surface is VM-vettable byte-for-byte (no f32 anywhere). Side view: x right, y up, orthographic. license_tier: ORIGINAL
