Nullohm makes room-temperature superconducting cable for national grids. Every metre carries current without loss, so the logo is the one graph that proves it.
The mark is a resistance curve: a line that falls off a cliff to zero. Cable batches are stamped with a curve derived from their batch code, so no two drums carry quite the same logo and all of them are recognisably the same family.
The stamp is a hash of the code passed through a sigmoid. The same code always gives the same curve.
Everything is black on a cold white. The whiteness should feel slightly too clean, like a lab at 4 a.m.
The only accent is the metal we replace. Copper appears wherever something is losing energy, and nowhere else.
Martian Mono is reserved for values that came off an instrument. If nobody measured it, set it in Archivo.
All rules, borders and curves share one weight, which keeps tables, labels and the logo in a single drawing system.
Resistance ends here. Zero point zero zero zero. We report what happened, and leave the adjectives to the competition.
No sparks, no glow, no blue energy. Electricity that is doing its job is invisible, and that is the entire product.
