Spec build · placeholder content · real render
Real-time reflections where the hardware allows it. Pre-rendered motion where it doesn’t. Identical choreography either way.
The criterion
A hero that dies on an ageing laptop caps the work in the mid sevens, however it looks on the machine it was built on. Performance is not the final phase of this build. It is the budget everything else spends from.
Not whether the API exists — whether an adapter answers. On this machine it does, so you get real-time reflections. On a five-year-old laptop it does not, and nobody ever sees a black rectangle.
The camera move is authored once, then handed to whichever renderer the visitor qualifies for. The choreography is the product. The renderer is an implementation detail.
Beauty that drops frames places nowhere. Every effect here is spent from a budget, and the budget is set by the slowest device we care about — not the fastest one we own.
