// Header-only and free of ESP-IDF: nothing here touches a peripheral, a task
// or NVS, so the host test in test/host/espos_formulas_test compiles the same
// code the firmware runs, and checks it against published reference values.
//
// The transform NODES that wrap these — Curve, DewPoint, Convert and the rest
// — live in espos_flow/transforms/ and are what you wire into a graph. This
// component is the arithmetic underneath, usable on its own.
//
// docs/transforms.md is the tour, including where each SensESP transform went.
