/**
 * RFC 0007 R26 — the naming grammar shared by the forward SVG export and the
 * reverse design audit. One grammar, written by one side and read by the
 * other, is what makes the Figma/Penpot round-trip lossless with zero API:
 *
 *     <Journey> ▸ <Screen> / <state>
 *
 * Identity is carried by contract *ids* (not human titles) so that
 * `parseFrameName(frameName(screen, state))` round-trips exactly. Screen and
 * state ids in JourneyGraph are drawn from `[\w.\-]+` (the same charset the
 * audit markers accept), so neither the " ▸ " nor the " / " separator can
 * occur inside an id.
