 ## [Unreleased]
 
+### Fixed
+- **Climate now respects latitude on both hemispheres** (T-1186) — a sign-convention bug made every northern hemisphere read as polar (+90°) and the southern hemisphere read as compressed northern tropics: temperate lakes at 76°S, ice only at the top of the world map. Temperature baselines, glaciation, and everything derived from them now band correctly north AND south of the equator — the same spot near the antarctic circle that used to derive as an 18 °C ice-free lake now comes out at 2 °C under light glaciation
+- **Lakes deepen from the shore** (T-1188) — lake shorelines no longer render as hard flat-blue step-edges: every lake cell now carries its settled-hydrology depth band, and the map shades lakes from pale at the water's edge to dark at the deepest point of the basin — the same visual grammar ocean coastlines already had. (Game version 0.4.0 → 0.4.1: old on-disk map caches refresh automatically)
+
 ### Added
 - **The Atlas remembers across restarts** (D-255, T-1183) — every map view you visit is now kept on disk as well as in memory: relaunch the game, reopen a body, and previously-visited zoom steps draw instantly from the local cache with no server round-trip — only genuinely new ground fetches. Storage stays tidy on its own: fine-grained views of a body you haven't visited in ~two weeks quietly reclaim their space, each body's deep-zoom footprint is capped, and the whole-body overview of every visited body is kept forever. The cache is update-safe by construction — entries from an older game version are silently refetched, never misread
 - **The stepped Atlas map** (D-255, T-1182) — the body map is rebuilt on the step-canvas pipe: opening a body lands on the whole-body Global view, and the mouse wheel walks six discrete zoom steps (Global → Region → District → Quarter → Block → 64 m Chunk), cursor-anchored, with edge-scroll and WASD panning and a hard full-zoom-out snap back to Global. Terrain draws texel-exact from the server's data canvas (no client-side scaling — the whole family of zoom-compensation bugs is structurally gone, ~9,400 lines lighter), while river courses and settlement markers stay crisp at constant pixel sizes on a separate annotation layer. While a new step loads, the previous view holds with a pending wash — no blank frames. Within one session, revisited views come from an in-memory cache; the disk cache that survives restarts is the next ticket (T-1183)
