## Final-context NPC review harness (pre-build gate).
##
## Stages all eight authored character models at portrait, conversation and
## crowd distance on both promoted maps, in day and night lighting. The normal
## crowd is hidden so each frame isolates the character and the venue behind it.
## Output is local QA art (put it under `tmp/` or `docs/screens/realism/`).
##
## Usage:
##   godot --path . --script res://src/test/capture_npc_review.gd -- \
##     --out=res://tmp/npc-review-1
##
## The guard character has no spawned NPC role; it uses the review-only
## `character_override` on NpcAvatar.
