+Released: 2026-10-01
+
+### Highlights
+- 修正 breaking 新闻状态显示：ticker 仅在当前滚动到 breaking 新闻时变红，展开面板始终保持蓝色。
+
+### Added / Fixed / Improved
+- 选中、焦点、关闭动画与 breaking 数据状态彻底分离，关闭新闻栏不再留下橙色边线。
+- breaking 新闻按过期时间重新计算，单条新闻卡片继续保留自身 breaking 红色样式。
+- 增加 ticker breaking 状态单测和浏览器关闭/重开验证。

+## [0.76.3] — 2026-10-01
+
+Released: 2026-10-01
+
+### Highlights
+- 修复新闻栏关闭后残留橙色边线的问题，明确 breaking、展开面板和新闻选择的状态边界。
+
+### Added / Fixed / Improved
+- ticker 保持中性，breaking 等级只作用于展开新闻面板整体背景和阴影。
+- 关闭新闻面板时清理选中故事和过期焦点状态，breaking 按新闻过期时间重新计算。
+- 增加 breaking 状态单测，保持新闻滚动、选择和面板动画行为不变。

 ### News ticker edge fading
 
-A separate pseudo-element paints the ticker background and horizontal rules, fading to full transparency outside the text bounds. The shell has no rectangular backdrop filter, box shadow, or text mask. The region label sizes to its content and the scrolling text follows directly without fading. Alert states change only the gradient rule color so they cannot reintroduce rectangular shadow edges.
+A separate pseudo-element paints the ticker background and horizontal rules, fading to full transparency outside the text bounds. The shell has no rectangular backdrop filter, box shadow, or text mask. The region label sizes to its content and the scrolling text follows directly without fading. The ticker stays neutral; breaking levels style the expanded news panel as a whole. Selection, focus and close animation do not mutate the breaking data state, which is recomputed from item expiry timestamps.
 
 Compute cards directly reuse the shared `.hud-panel` background, border, shadow, and glass treatment. Summary, essentials, and detail areas add no separate black surface. Their headers share inset spacing with the layer panel through `.hud-panel__header--inset` / `.layer-panel-header`; primary numbers remain prominent and essential information stays visible.

 ### 新闻栏端部渐变
 
-新闻栏的底色与上下细线由独立伪元素绘制，两端在正文范围之外渐变到完全透明；外框不使用矩形 backdrop-filter、box-shadow 或文字遮罩。地区标签按内容占宽，正文紧接标签，滚动文字不做渐隐。警报状态只改变渐变细线的颜色，避免重新引入矩形阴影边界。

 算力卡片外观直接复用共享 `.hud-panel` 的背景、边框、阴影和玻璃效果，摘要、基础信息及详情区不再叠加单独黑底。标题栏与图层面板共用 `.hud-panel__header--inset` / `.layer-panel-header` 的内边距；主数字继续突出，基础信息保持常显。
