C1-GEO-05 Layout Control — Regions, Boundaries, and Adjacency

Public page: docs/continents/caerlon/geography-and-maps/regions-boundaries-and-adjacency.md

The page sequence is title, C1-M05, boundary explanation, regional profiles, numbered-site key, C1-D05 and adjacency table, shared-water interfaces, C1-I04, legacy names, crossing recognition, PF2e treatment, and map scope.

C1-M05 uses a clean semantic vector base. Mainland polygons must not overlap. Every site marker must lie inside exactly one assigned region. Every visible boundary segment must resolve to an adjacency record and a normalized boundary-type record. Broken Chain Approaches remain offshore.
