Machines begin as pictures. Claims begin somewhere else.
Visual engineering concepts, vehicles, energy systems, habitats, and industrial architectures live here with an explicit boundary between what is depicted, what physics supports, what remains hypothetical, and what would kill the design.
A visual concept is allowed to be audacious. Its evidence label is not.
Every invention entry preserves authorship and visual intent while publishing its assumptions, first-order bounds, limitations, test path, and public-disclosure boundary. A rendering never self-promotes into a verified mechanism.
