+### Visual Evidence And Style Consistency
+
+- Treat user-provided screenshots and images as primary visual evidence. If a
+  screenshot contradicts written text, inspect the image first and explicitly
+  call out the mismatch before deciding what to change.
+- If a referenced screenshot path cannot be opened, do not infer image content
+  from the filename, alt text, surrounding prose, or memory. Search the current
+  thread attachments, repository, and obvious local attachment/download
+  locations; if the image still cannot be found, ask for the file or report the
+  blocker instead of guessing.
+- Same-category UI surfaces must use one visual system per product area. Badges,
+  chips, pills, tags, status labels, small buttons, cards, panels, and toolbar
+  controls should reuse the shared component, shared token, or established CSS
+  owner for that area instead of introducing a page-local lookalike.
+- `scripts/harness/frontend-rules-check.sh` warns when semantic
+  `badge` / `chip` / `pill` / `tag` / `status` selectors appear outside the
+  approved React and Earth CSS owner files. A warning means the reviewer should
+  either move the style into the shared owner or document why this is a genuinely
+  new visual family.
+
+### Earth I18n Harness Rules
+
+Earth i18n work must validate rendered behavior, not only static text lookup.
+Agents often miss dynamic strings that are created after initial page load, so
+the smoke treats these as first-class i18n surfaces:
+
+- **Visible text and attributes**: translated checks must include `innerText`
+  plus `title`, `aria-label`, `placeholder`, and `alt`. Tooltips and icon-only
+  buttons are user-facing copy, not implementation details.
+- **Dynamic detail cards**: info cards opened from Earth markers, cruise cards,
+  BGP markers, compute centers, vessels, and news must render field labels,
+  status values, source tags, action buttons, and disabled/tooltips in the active
+  language.
+- **English content safety**: English mode must not fall back to Chinese news
+  titles, summaries, feed names, measure words, or generic status labels. If no
+  English localization exists, hide the item or use a neutral English fallback.
+- **Brand assets**: locale switching must update both text and image assets.
+  The default Earth HUD brand uses `title-zh.png` for Chinese and `title-en.png`
+  for English while keeping the same top-left layout and logo position.
+- **Controls and state**: switch/segmented-control visuals must follow the real
+  checked/pressed state after both direct clicks and programmatic panel changes.
+  A control is not valid if the state changes but the thumb, active pill, or
+  `aria-*` state stays stale.
+- **Runtime copy entrypoints**: dynamic status, loading, startup, and error copy
+  must enter through `earthMessage(...)` plus the centralized
+  `EARTH_MESSAGE_TEMPLATES` map. Do not hide direct strings behind
+  `showStatusMessage`, `queueStatusMessage`, `showGestureStatusMessage`,
+  `showError`, `setLoadingMessage`, `resolveStartupMessage`, `startupMessage`,
+  or `earth:status` events.
+- **Capsules and tags**: pills, tags, chips, badges, and small buttons must not
+  overflow their panel. Prefer a slightly wider owning panel for important
+  status information; otherwise use `min-width: 0`, wrapping, or ellipsis with a
+  translated tooltip.
+
+Current frontend smoke explicitly covers the Earth English locale flow: brand
+image swap, settings language controls, panel switch visual sync, English news
+filtering, English detail-card text and tooltips, and TV default/source labels.

+In English mode, Earth news must render only English title/summary text.

 The news panel, ticker, and news cruise must consume `items` / `cruise_items` from the same `/api/v1/news/earth-feed` response instead of keeping separate regional caches. `news.js` builds a refresh request key from region, category, source, and limit; only concurrent requests with the same key reuse the promise, and stale responses from an older region are dropped by token. Source filtering is also region-scoped: when the user moves from Asia Pacific to Europe or another region, source IDs saved for the old region must not be appended to the next fetch. After the new payload arrives, the saved source list is intersected with the available `sources`; if the intersection is empty, the current region falls back to all available sources. This keeps the ticker, panel, and cruise cards aligned after region switches.

 Settings that affect visual layers and surface interaction (terrain opacity, day/night mode, satellite display style, satellite idle breathing, real satellite altitude, track display, hover tooltip mode, etc.) are read during initialization and applied immediately.
 
+Language preference is the exception: Earth language is not a private `planet.earth.settings.v2` field. It shares `planet-locale` with Docs/Admin. When language changes, `i18n.js` updates `document.documentElement.lang`, translates static and dynamically inserted DOM, synchronizes language button state, and passes the current locale to news requests. The news module refreshes after a language change so an English UI does not reuse a Chinese news payload.
+
 The surface hover tooltip preference is persisted by `controls.js` as `shared.surfaceHoverInfoMode`, while `main.js` composes the actual tooltip in the globe-surface hover branch. `Country` shows country details only when a country polygon is hit and stays silent over ocean; `Position` shows latitude, longitude, and sampled terrain elevation and clears country-boundary hover; `Full` shows country + position on land and position over ocean.
 
 The real satellite altitude preference is persisted by `controls.js`, while the rendering state lives in `satellites.js`. When enabled, the real radius from SGP4 is compressed logarithmically into the current Earth visual radius range. When disabled, satellite dots, trails, and predicted orbits all return to the legacy same-sphere display. Toggling this setting must refresh satellite positions and clear trail buffers so a trail never mixes both height models. `maxRealAltitudeOffset = 25` is a visual cap tuned for the current camera and `earthRadius = 100`: GEO / MEO remain clearly higher than LEO, but the highest orbits stay within about 25% beyond the globe radius so selection targets, red trails, and the globe do not feel disconnected.
