+## 0.25.2
+
+Released: 2026-04-10
+
+### Highlights
+
+- Refined the Earth HUD operator polish so settings now behave like a true bounded menu, HUD panels render at the correct scale from the first frame, and dragged panels animate cleanly into and out of maximized layout targets without drifting to screen edges.
+
+### Improved
+
+- Improved [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html) by precomputing the initial `--hud-scale` before Earth CSS loads, so HUD panels no longer flash at full size before shrinking to the target scale.
+- Improved [frontend/public/earth/css/hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css) by cleaning up duplicated settings-modal close-button styles, aligning the settings title with the shared HUD title system, and constraining the settings sheet to a stable centered width instead of viewport-relative modal sizing.
+
+### Fixed
+
+- Fixed [frontend/public/earth/js/controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js) so dragged HUD panels now fly from their dragged positions into maximized layout targets, closed panels stay out of the transition, and restoring layout clears drag overrides back to the initial positions.
+- Fixed [frontend/public/earth/js/controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js) and [frontend/public/earth/css/hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css) so layout transitions no longer visibly stick to screen edges before landing; the FLIP motion now composes with the existing corner transforms instead of fighting them.
