/**
 * The DELVE Forge — one button, a form, and a complete dungeon injected into the world.
 *
 * Everything the generator knows becomes real Foundry content in one pass:
 *   • a folder per dungeon, holding its scenes, actors and journal
 *   • one scene per area, walls and lighting placed, raised via the VANITY Forge
 *   • encounter actors, in that folder rather than scattered
 *   • a JournalEntry — GM truth, one page per area, the ending — which IS the adventure
 *
 * The journal is the deliverable. Scenes without it are a pile of maps; the journal is what a
 * GM actually reads, and it is written so it can be read cold.
