+#### Next.js 15 Breaking Change: Async Params
+**Critical**: Next.js 15 changed `params` and `searchParams` to be **async** (Promise type).
+- In page components: `params: Promise<{ locale: string }>` and `searchParams: Promise<{ key?: string }>`
+- In API routes: `{ params }: { params: Promise<{ id: string }> }`
+- **Always await these params before using them**:
+  ```typescript
+  // ✅ Correct
+  const { locale } = await params;
+  const resolvedSearchParams = await searchParams;
+  const quarter = resolvedSearchParams.quarter || 'default';
+
+  // ❌ Wrong (causes runtime errors in Next.js 15)
+  const { locale } = params;  // params is a Promise, not an object
+  const quarter = searchParams.quarter;

+### Creating New Pages (Next.js 15)
+When adding new pages in the App Router, remember that **params and searchParams are Promises**:
+
+```typescript
+// Page component structure
+interface PageProps {
+  params: Promise<{ locale: string; id?: string }>;
+  searchParams: Promise<{ [key: string]: string | string[] | undefined }>;
+}
+
+export default async function MyPage({ params, searchParams }: PageProps) {
+  // MUST await params and searchParams
+  const { locale, id } = await params;
+  const { filter, sort } = await searchParams;
+
+  // Now you can use the values
+  // ...
+}
+
+// For generateMetadata
+export async function generateMetadata({
+  params
+}: {
+  params: Promise<{ locale: string }>
+}) {
+  const { locale } = await params;
+  // ...
+}
+```
+
+For API routes with dynamic parameters:
+```typescript
+export async function GET(
+  request: Request,
+  { params }: { params: Promise<{ id: string }> }
+) {
+  const { id } = await params;
