/**
 * /enso, on the bytes that ship.
 *
 * The page's claim is drawn in its hero: a request comes in, Enso weighs it, it
 * takes one lane — write, decide or act — and comes out with its reason. So the
 * gate asks the drawing what the copy says: three lanes, one taken, Decide
 * marked as the lane still being built; the request turns when motion runs and
 * stands still when it does not; the loud control leans only toward a fine
 * pointer. The measurement — the lead, the boards and the ceiling, read from
 * the research runs when the page opens — is e2e/gates/ladder.spec.ts's. Then
 * the two things every page owes: nothing thrown, nothing wider than a phone.
