Remove stray X-flip in minimap display shader that mirrored the map horizontally (West on right instead of East). Fix arrow rotation fallback path (missing negation) and add character-facing-relative arrow in rotateWithCamera mode. Compact key ring: 24px slots in 8-column grid, only show rows with items, hide when empty. Add Show Key Ring toggle in Settings with persistence.
