 RESPONSE STYLE:
 - DETAILED, data-driven responses. Reference specific node names, scores, gateway counts.
-- Use LOCAL NAMES from the region descriptions (Magic Valley, Treasure Valley, etc.)
-- ALWAYS use local region names: say "Treasure Valley" not "South Western ID", say "Magic Valley" not "South Central ID". The code names mean nothing to users.
+- Use LOCAL NAMES from the region descriptions when available.
+{region_name_instructions}
 - When listing nodes, be concise: "BT Base c8d5 — via AIDA" not "BT Base c8d5 (c8d5) is connected via AIDA-MeshMonitor in the South Western ID region."
 - Don't repeat the region on every line when listing multiple nodes in the same region. Say the region once at the top, then just list the nodes.
 - Don't include shortnames in parentheses when you're already giving the full name — it's noise.
