+# 011 — NavMenu UI
+
+## Summary
+
+Build out the NavMenu frontend component for managing settings, presets, and CSS,
+per the README's block diagram (NavMenu occupies its own column alongside the rest
+of the dashboard).
+
+## Scope
+
+- Settings panel: colour scheme picker, CSS import (file/text input) + list of
+  imported/linked CSS with delete where applicable.
+- Presets panel: list/create/switch/delete profiles ([009](009-presets-profiles.md)),
+  showing each profile's param/metric declaration counts and saved dashboards.
+- Wire to the settings/profile/CSS APIs from
+  [008](008-settings-model.md)/[009](009-presets-profiles.md)/[010](010-css-management.md).
+- Apply the active colour scheme / imported CSS to the app shell at runtime.
+
+## Acceptance criteria
+
+- Switching active profile in the UI changes engine state (declared params/metrics)
+  without a manual restart, or clearly communicates that a restart is needed if
+  that's the chosen design from [009](009-presets-profiles.md).
+- Importing/deleting CSS in the UI is reflected immediately in the rendered app.
+
+## Depends on
+
+- [008 — Settings model](008-settings-model.md)
+- [009 — Presets / profiles](009-presets-profiles.md)
+- [010 — CSS import/management](010-css-management.md)
