// Script bank — FACADE over the shared content SSOT (src/engine/data/story-content.json).
//
// All the operator's shift material now lives in story-content.json (the single source
// shared with the native Swift twin). This module re-exports it under the original names
// + types so consumers are unchanged, keeps the persona-token form (`{node}` etc. — see
// persona.subst), and retains the small code-side helpers (genHash, foreshadow/arrival/
// combat lookups, computed ghostlink strings) that are logic, not content.
//
// Worldbuilding sources: NeuroVim FRAGMENTS 01-10, Mission briefings, THE RAVEN.
