Recipe: toggle wireframe

r_wireframe changes material wireframe state. r_showtris is the scene-level debug switch.

Code

const renderVars = RenderVars.getInstance();

const current = renderVars.get('r_wireframe') ?? 0;
renderVars.set('r_wireframe', current >= 0.5 ? 0 : 1);

Both variables are debug category and are not persisted as durable render preferences. If you add a key binding, register it through InputSystem and remove its context/handler during teardown rather than attaching an unmanaged global DOM listener.
