Current Mechanism
The current compact browser and hardware reference is Cartilage Core. Its public source repository places the single-file WebGL1 model beside a hardware paper, SystemVerilog RTL, and Verilator testbench, while keeping browser rendering evidence distinct from RTL clock behavior.
The Artifact
The linked demo was a GLSL rendering of a nano-FPGA fabric: a repeated cell field where the visual pattern is meant to expose local structure instead of hiding it behind a block diagram.
The important part is the executable surface. A shader can draw the repeated geometry, show tile roles, and make the fabric readable as a live grid rather than a static illustration.
Why Use a Shader
A fabric made from many local cells is hard to explain with a single schematic. WebGL is a useful medium because it can render the whole field while preserving repeated local detail.
That makes the renderer part of the engineering work. It is a way to inspect tiling, orientation, role encoding, and local connection rules at the scale where the machine actually exists.
What The Render Gives
The useful output is a stable visual grammar: repeated cells, roles, orientations, and neighborhood connections can be inspected, shared, and compared with later Cartilage renders.
