+# Sound Bridge Notes
+
+Glitch University uses a host-managed sound system (Howler-based) with string sound keys, for example:
+
+- `playSound('ui.button_click')`
+- `playSound('ui.button_hover')`
+
+## Recommendation
+
+Treat sound as an optional host integration:
+
+- Use a small wrapper function in the component (`safePlaySound`) that checks whether a host sound function exists.
+- No-op when unavailable (standalone dev should still run).
+- Keep sound identifiers as strings/constants so they match host definitions.
+
+## Example Pattern
+
+```ts
+type PlaySound = (id: string) => void;
+
+export function safePlaySound(playSound: PlaySound | undefined, id: string) {
+  try {
+    playSound?.(id);
+  } catch {
+    // Ignore host sound errors in standalone/local mode
+  }
+}
+```
+
+## Unknowns to Confirm Later
+
+- How the host exposes `playSound` to glitch-components (prop, context, global import, event bus)
+- Which sound keys are safe/standardized across experiences
+- Whether completion/reward sounds are triggered by host or component
