+## 0.21.6
+
+Released: 2026-03-27
+
+### Highlights
+
+- Refined the Earth page interaction loop with object-driven legend switching, clearer selection feedback, and cleaner HUD copy/layout behavior.
+- Improved the Earth info surfaces so status toasts, info-card interactions, and title/subtitle presentation feel more intentional and easier to scan.
+
+### Added
+
+- Added click-to-copy support for info-card labels so clicking a field label copies the matching field value.
+- Added runtime-generated legend content for cables and satellites based on current Earth data and selection state.
+
+### Improved
+
+- Improved Earth legend behavior so selected cables and selected satellite categories are promoted to the top of the legend list.
+- Improved legend overflow handling by constraining the visible list and using scroll for additional entries.
+- Improved info-panel heading layout with centered title/subtitle styling and better subtitle hierarchy.
+- Improved status-message behavior with replayable slide-in notifications when messages change in quick succession.
+
+### Fixed
+
+- Fixed info-card content spacing by targeting the actual `#info-card-content` node instead of a non-matching class selector.
+- Fixed cable legend generation so it follows backend-returned cable names and colors instead of stale hard-coded placeholder categories.
+- Fixed reset-view and legend-related HUD behaviors so selection and legend state stay in sync when users interact with real Earth objects.
