+/**
+ * STYLE-001 Phase 3: TokenPicker
+ *
+ * Reusable dropdown component for selecting a design token to bind to a CSS property.
+ * Displays the current token (with colour swatch preview for colour tokens) and opens
+ * a searchable, grouped list of all available tokens.
+ *
+ * This component is fully dumb — it receives tokens as plain data and fires callbacks.
+ * Token resolution (var() → actual CSS value) must be done by the caller before passing
+ * items in. This keeps noodl-core-ui free of editor-specific model dependencies.
+ *
+ * Usage:
+ *   <TokenPicker
+ *     tokens={allTokens.map(t => ({ ...t, resolvedValue: model.resolveToken(t.name) }))}
+ *     selectedToken="--primary"
+ *     onTokenSelect={(cssVar) => applyValue(cssVar)}

+ *   on subsequent calls, avoiding repeated DOM mutations.

+ * UBA-007: DebugStreamView
+ *
+ * SSE-based live debug log viewer for UBA backends.
+ * Connects to the backend's debug_stream endpoint via UBAClient.openDebugStream()
+ * and renders a scrollable, auto-scrolling event log.
+ *
+ * Features:
+ * - Connect / Disconnect toggle button
+ * - Auto-scroll to bottom on new events (can be overridden by manual scroll)
+ * - Max 500 events in memory (oldest are dropped)
+ * - Clear button to reset the log
+ * - Per-event type colour coding (log/info/warn/error)

+ *
+ * Editor-side panel for the Universal Backend Adapter system.
+ * Provides two tabs:

+ *   - Debug: Live SSE event stream from the backend's debug_stream endpoint
+ *
+ * Schema discovery flow:
+ *   1. Read `ubaSchemaUrl` from project metadata
+ *   2. If absent → show SchemaLoader UI (URL input field)
+ *   3. Fetch + parse the schema with SchemaParser
+ *   4. On parse success → render ConfigPanel
+ *
+ * Config persistence flow:
+ *   1. Load `ubaConfig` from project metadata as initialValues
+ *   2. ConfigPanel.onSave → store in metadata + POST via UBAClient.configure()
+ *
+ * Project metadata keys:
+ *   - 'ubaSchemaUrl'  — URL or local path to the UBA schema JSON
+ *   - 'ubaConfig'     — saved config values (nested object)
