Half-sun on left edge, planets left-to-right with radius-based sizing (Earth = 24px reference, unclamped — gas giants fill the view). Globe textures loaded from wiki at runtime. Double-click on reach map opens system view. M closes atlas from any screen, ESC navigates back. Fixes Godot 4.6 type inference parse errors in main.gd (var zoom/speed). Uses physical_keycode throughout for layout-independent key handling. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
