- Each NPC now has a description (who they are), disposition, and significance
(why they matter), plus a deterministic per-NPC seed.
- New procedural black-and-white art: npcPortraitSVG (stencil "ident" mugshots,
varied head/hair/eyes/mouth/accessory) and itemIconSVG (line-art icons by
OTEM category), with data-URI variants.
- Field Dossier renders NPC character-sheet cards and item cards with art.
