Interpolation method and scope

V1 supports ascending or equal endpoints in the same unit: px or rem. Viewports use px. Rem output requires the visible root-size assumption. The preferred term uses a fixed intercept plus vw coefficient; calculations retain full precision and display at most five decimals.

The output is a mathematical interpolation, not a claim that the chosen sizes are universally optimal or accessible for every design.
