Populate cast[] (kind:'npc') for every Continuum scenario, transcribed
from the gm-utility NPC sources — normalising the two schemas (console
{id,name,ess,sec} and module {name,tag,secret}) into
{ id, name, kind, note, secret? }. 57 NPCs total. Pregens/PCs excluded
(separate character-sheet system).
No cast UI consumer yet — the design reserves scenario.cast for a future
cast dashboard, so this is a data-model port guarded by
tests/scenarios/cast.test.js (shape + unique ids). 131 tests pass.
