 Normal borders, coastlines, claim lines, highlights and landing points use `earth-surface.js` to share the HD sphere UV-triangle surface. Borders draw after the texture but before landing points. Highlight lines are always transparent-queue objects with depth testing, preventing through-globe display or overpainting markers. Geometry is computed and cached at construction, not reprojected per frame. See the [render-layer specification](earth-render-layer-order.md).

+### News ticker edge fading and breaking state machine
 
-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 previous breaking rule was global shell promotion: if the payload contained any unexpired breaking story, the highest level (`critical > breaking > watch`) was applied to the ticker or expanded panel. That made a closed panel, or a ticker currently showing a normal story, retain an orange/red state. `breaking_expires_at` eventually cleared the state, while selection, opening and closing did not change the underlying breaking data.
+
+The current state machine keeps data, ticker visibility, panel lifecycle and selection separate:
+
+- `getNewsBreakingState()` derives the data state from `items` and `cruise_items`, ignores expired stories, and ranks `critical > breaking > watch`. The expiry timestamp only schedules the next recomputation.
+- A ticker viewport watcher runs every 120 ms and chooses the item with the greatest viewport overlap, breaking ties by distance to the viewport center. Only when that current item has a non-`none` level does the ticker switch its horizontal rules to `has-breaking-*`; it returns to neutral as soon as the current item is not breaking.
+- The panel lifecycle is `closed → opening → open → closing → closed`. Opening and closing control morphing, visibility and ticker hiding; they do not mutate the breaking data. During `opening/open`, the current card DOM stays stable while incoming payloads are deferred and applied once on close, so realtime updates cannot rebuild a hovered card.
+- `selectedCruiseStoryId` is independent of breaking severity. Selection, focus, hover and close only change the selected story and reading position; close also clears the selection and filter popover.
+- The expanded panel always keeps its blue glass surface. Breaking colors remain on the matching story cards, so opening the panel never turns the entire glass panel red; the ticker can still show a red signal when the currently scrolling story is breaking.
+
+The glass-reflection pulse is implemented: when the current ticker story enters a breaking state, its `::after` emits a low-frequency, limited-amplitude full-width horizontal red/amber sweep and pulse; the matching breaking card gets a single glass reflection sweep through its own `::after`. The panel base remains blue and there is no permanently flashing full border. `prefers-reduced-motion` disables the animation and keeps a low-intensity static cue. This visual sub-state stays attached to the current breaking story and matching card, independent of whether the panel is open.
 
 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。
+
+此前的 breaking 规则是：只要本次 payload 中存在未过期的 breaking 新闻，就按 `critical > breaking > watch` 取最高等级，把等级直接映射到新闻壳层。这样会让整条 ticker 或展开面板在当前显示的新闻并非 breaking、甚至面板已经关闭时仍保留橙/红状态，造成“关闭后残留边缘”和“整个面板变色”。`breaking_expires_at` 到期后才清除该状态；选中、打开和关闭不会改变 breaking 数据本身。
+
+当前状态机将数据态、ticker 显示态、面板生命周期和选中态分开：
+
+- 数据态由 `getNewsBreakingState()` 从 `items` 与 `cruise_items` 合并计算，只接受未过期项目，并按 `critical > breaking > watch` 排序；到期时间只负责安排下一次重新计算。
+- ticker 的显示态由滚动视口 watcher 每 120ms 取视口内重叠最多、距离中心最近的当前项目。只有当前项目的 breaking 等级非 `none` 时，ticker 的上下细线才切换为对应的 `has-breaking-*` 颜色；当前项目离开后立即恢复中性。
+- 面板生命周期 `panelPhase` 只有 `closed → opening → open → closing → closed`。打开/关闭只控制形变、可见性和 ticker 的隐藏，不改变 breaking 数据态；进入 `opening/open` 后保留当前卡片 DOM，后台 payload 先暂存，关闭时再一次性应用，避免 hover 卡片被实时更新重建。
+- `selectedCruiseStoryId` 独立于 breaking 等级。选择、聚焦、悬停和关闭只更新选中项与阅读位置；关闭时清空选中项及筛选弹层。
+- 展开面板始终使用蓝色玻璃底。breaking 只在对应新闻卡片上使用等级颜色，因此点开面板不会把整块玻璃染成红色，之后滚动到 breaking 新闻时仍可让 ticker 显示红色提示。
+
+breaking 的玻璃反射脉冲已实现：ticker 当前项目进入 breaking 状态时，`::after` 以低频、有限幅度的全宽横向扫光带增强并闪烁；展开面板中只在对应 breaking 新闻卡片上用 `::after` 扫过一条玻璃反射带。面板底色保持蓝色，不使用持续闪烁的整圈边缘；`prefers-reduced-motion` 下停用动画并保留低强度静态提示。该视觉子状态挂在当前 breaking 项目和对应卡片上，不与面板是否打开耦合。
 
 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。
