Engineering Principles

Tolerances we don't loosen.

1

Precision before speed, always

Every component ships to a measured spec — ±1px alignment on the grid, no eyeballing, no exceptions in review.

2

One material, machined cleanly

Cards are cut from a single token set — hairline borders, fixed radii, zero ad-hoc hex values across the system.

3

The accent stays rare

Red marks the one thing that matters per surface — used once, deliberately, never as decoration.

4

It still works in twenty years

We tool for repair, not replacement — 0 breaking renames, parts re-fit older releases without forks.
