-# Popped-out tabs don't apply the active colour scheme/theme at all
-
-Reported: clicking "Open in new tab" (`PopOutButton`) opens a tab that doesn't match the current colour scheme/theme at all.
-
-Root cause: applying the colour scheme (`applyColorScheme`, `document.documentElement` class) and injecting any active custom theme's CSS is done entirely inside `useSettingsPanel()` (`webapp/src/lib/useSettingsPanel.ts`), and that hook is only ever called from `NavMenu.tsx:34`. Every popped-out standalone route (`StandalonePage` in `App.tsx`, used by `StandaloneLog`, `StandaloneParams`, `StandaloneRanged` for metrics/dashboards) wraps its children in `DocsNavProvider` only — it never renders `NavMenu` and never calls `useSettingsPanel()`. So a popped-out tab never sets the colour-scheme class or injects the custom theme `<style>` tag; it just renders with no theme applied.
-
-## Acceptance criteria
-- Opening any section in a new tab (`log`, `params`, `metrics`, `dashboards`) applies the same colour scheme and, if active, the same custom theme CSS as the tab it was opened from.
-- `StandalonePage` (or each standalone route) calls `useSettingsPanel()` (or otherwise triggers `applyColorScheme`/custom-theme injection) on mount, without needing to render the full `NavMenu` settings UI.
-- Theme application in the popped-out tab stays live if settings change while it's open (consistent with how the main window already behaves via `useSettingsPanel`), not just correct at initial load.
-- No regression to the main window's existing theme behavior via `NavMenu`.
