`ShaderMaterial` prepends three's own built-ins — projectionMatrix,
modelViewMatrix, position — but it does NOT prepend the custom uniforms declared
in the `uniforms` object. `uPixelRatio` was in that object and never declared in
the GLSL, so the vertex program failed to compile with
ERROR: 0:79: 'uPixelRatio' : undeclared identifier
and the whole satellite dome silently drew nothing on the deployed site while
every other layer carried on. The only symptom was a console error nobody was
reading — which is exactly why the deploy check now opens the page and greps the
console rather than trusting a 200.
Found by screenshotting the LIVE site after deploying, not by any test: no test
in this repo compiles a shader, `npm run build` cannot, and `ui-smoke` passed
because the page boots fine with one layer missing.
Verified after the fix at two hours on two boards: zero shader errors, where the
deployed build had one on every load.
