+## [0.29.1] — 2026-04-20
+
+### ✨ Highlights
+- Earth 加载状态条改成单一队列式通知面板，加载阶段不再因为步骤文案变化而回缩，也不会被其他通知打断
+- 调整 brand panel 的呈现方式与昼夜/选中态可读性，让品牌区更自然、交互高亮在白天和黑夜里都更稳定
+
+### 🔧 Improvements
+- 移除旧的地球加载浮层结构，统一由 HUD 状态消息承载三点脉冲加载过程
+- brand panel 改为无边框品牌层，仅保留轻微氛围光，不再因为非常规尺寸显得像第五块功能面板
+- 温和收敛地球昼夜材质与主背光强度，保留昼夜辨识度的同时提升白天地表纹理和夜面交互可见性
+
+### 🐛 Fixes
+- 修复加载地球时通知条在步骤切换中反复缩短、其他状态消息抢占加载流程的问题
+- 修复海缆、登陆点和 BGP 选中高亮在黑夜中过暗、在高光中过亮导致难以辨识的问题
+
+---
