The rail itself
Camber is a rail, not a personality.
On this yard a rail is the curve from leading edge to trailing edge, read on packed Antelope Valley dirt, not on a mat that never met alkali.
We dust the sole, we hit a tray we keep crusted like a Palmdale morning, and we watch whether the rail plows or leaves. A prow is high. A sled is low. The number is that behavior, not a nickname from a catalog.
High rails get flattened until the prow shuts up. Low rails keep their sled. A brochure curve that ignores the tray gets parked. We do not 'warm it up a little' as a kindness to a photo.
