 ## [Unreleased]
 
+### Fixed
+- **The Atlas map now fills the screen properly** (T-1189, T-1192) — the whole-body Global view fit-scales and centers in the viewport instead of sitting small in the top-left corner, and the legend sits beside the map instead of on top of it. The Region zoom step no longer shows the planet repeating side-by-side or smearing into stripes past the poles — the map view is capped at the body's actual size and letterboxed, so what you see is the planet once, correctly framed
+
 ### 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)
