+## Title
+
+fix: address review feedback — params, theme flash, Monaco theme, auth race, socket cleanup, gradient tokens + merge upstream/main
+
+---
+
+## Summary
+
+Six fixes addressing the merge review feedback, plus a merge of upstream/main (7 file conflicts resolved). All six fixes are preserved after the merge. The branch is up to date with `upstream/main`, no remaining conflicts.
+
+---
+
+## Must-fix (blocking)
+
+### 1. `params` not awaited in ModulePage (Next.js 15 compat)
+
+**Commit:** `9e47097` | **File:** `apps/web/src/app/app/tracks/[trackId]/modules/[moduleId]/page.tsx`
+
+**Problem:** `ModulePage` was a Client Component destructuring `params` synchronously:
+```tsx
+export default function ModulePage({ params }: { params: { trackId: string; moduleId: string } }) {
+```
+
+In Next.js 15, `params` becomes a Promise. This code would break on upgrade.
+
+**Fix:** Since we're on React 18 (`use()` not available), we can't use `use(params)` in a Client Component. Instead, the page was split:
+- `page.tsx` → async Server Component that `await`s params and passes them as plain props
+- `module-page-content.tsx` → new Client Component (`"use client"`) receiving `{ trackId, moduleId }` as regular props
+
+This works identically on Next.js 14 today (awaiting a plain object resolves immediately) and will work on Next.js 15 after upgrade with zero changes.
+
+**Scope:** Grep of the entire `apps/web/src/app/` tree confirmed this was the **only file** destructuring `params` or `searchParams` — no other fixes needed.
+
+**Post-merge update:** After merging upstream/main, the inner Client Component was updated to use upstream's tRPC queries (`trpc.tracks.getById.useQuery`, `trpc.modules.getById.useQuery`) instead of the old mock data hooks, since upstream had already replaced the mock data layer.
+
+---
+
+### 2. Dark-mode flash on light-mode load
+
+**Commit:** `6e0d392` | **File:** `apps/web/src/app/layout.tsx`
+
+**Problem:** `<html>` had a hardcoded `className="dark"`. The `ThemeProvider` toggles the `dark` class via `useEffect` — which runs *after* hydration. A user with a saved light-mode preference would see a dark page flash before React corrected it.
+
+**Root cause analysis:**
+- Theme preference is persisted via Zustand store → `localStorage("unvibe-theme")` → values `"dark"` or `"light"`
+- Zustand initialized on client only (hydration), so the server always rendered `className="dark"`
+- No inline script existed to read the stored preference before first paint
+
+**Fix (3-part):**
+
+1. **Removed `className="dark"`** from `<html lang="en">` — the server no longer hardcodes dark mode
+2. **Added `suppressHydrationWarning`** to `<html>` — silences the false-positive hydration mismatch warning. The warning would fire because our inline script (step 3) mutates the DOM before React hydrates, causing the server-rendered class and client class to differ. This is intentional and harmless — `suppressHydrationWarning` silences just that one attribute on `<html>`.
+3. **Added blocking inline `<script>`** before `<body>` content:
+   ```js
+   (function(){
+     try {
+       var t = localStorage.getItem("unvibe-theme");
+       if (t === "light") document.documentElement.classList.remove("dark");
+       else document.documentElement.classList.add("dark");
+     } catch(e) {}
+   })()
+   ```
+   This runs synchronously before React hydrates, reads the persisted preference, and sets the correct class on `<html>` immediately — zero flash.
+
+**What didn't change:** The existing `useEffect` in `ThemeProvider` still handles class toggling when the user changes theme after load. The inline script only covers the initial paint.
+
+**Verification:** Hard-refresh the page in light mode — the page loads directly in light mode with no dark flash.
+
+---
+
+### 3. Monaco editor ignores theme setting
+
+**Commit:** `4c8994c` | **File:** `apps/web/src/components/features/code-editor.tsx`
+
+**Problem:** The Monaco editor had `theme="vs-dark"` hardcoded. Toggling the app to light mode left the code editor in dark mode — a visual inconsistency.
+
+**Fix:**
+```tsx
+import { useUIStore } from "@/stores/ui-store";
+// ...
+const darkMode = useUIStore((state) => state.darkMode);
+// ...
+<Editor theme={darkMode ? "vs-dark" : "light"} ... />
+```
+
+Now the editor's theme tracks the app's theme toggle in real time.
+
+**Post-merge formatting:** Upstream/main reformatted the component's function signature to multiline. Both changes are preserved in the merged result.
+
+---
+
+### 4. `asChild` + `onClick` race condition in auth flow
+
+**Commit:** `4ac870f` + merged via `1269c6f` | **Files:** `apps/web/src/app/auth/signin/page.tsx`, `apps/web/src/app/auth/signup/page.tsx`
+
+**Original problem:** Both auth pages used:
+```tsx
+<Button asChild onClick={signIn}>
+  <Link href="/app/dashboard">Enter mock workspace</Link>
+</Button>
+```
+With `asChild`, the Button renders as a `<Link>`. The `onClick` (calling `signIn()` from the mock auth store) could race with the Link's native navigation — `signIn` might not fire before the browser navigates.
+
+**Fix (original):** Removed the `asChild`/`Link` wrapper. Used a plain `<Button>` with `onClick={() => { signIn(); router.push('/app/dashboard'); }}`. Added a TODO for when real NextAuth wiring replaces the mock.
+
+**Post-merge resolution:** Upstream/main had already replaced both pages with real auth forms (email/password inputs, validation, loading state, error display, real `next-auth/react` `signIn` for OAuth). The upstream version naturally avoids the `asChild` race — it uses `onClick={handleSignIn}` on a plain `<Button>` with no Link wrapper. We accepted upstream's version in the merge. Our TODO was retired since real auth is already wired.
+
+The merged result:
+- Real OAuth buttons (`signIn("github")`, `signIn("google")` with `next-auth/react`)
+- Real email/password form with validation (check `handleSignIn`/`handleSignUp`)
+- Loading states with `LoadingPanel`
+- Error messages for invalid credentials
+- All `asChild`/Link patterns eliminated
+
+---
+
+## Minor (cleanup)
+
+### 5. Dead socket wiring in war-room-live
+
+**Commit:** `9aa842f` | **File:** `apps/web/src/components/features/war-room-live.tsx`
+
+**Problem:** `useEffect` called `getSocket().connect()` and `socket.disconnect()` in cleanup, but no socket event listeners were ever registered. The only data coming into the component was from a `setInterval` pushing mock messages. The socket calls were dead code.
+
+**Fix:**
+- Removed `import { getSocket } from "@/lib/socket/client"` (eliminates an ESLint `no-unused-vars` warning)
+- Removed `const socket = getSocket()` and `socket.connect()` from the effect body
+- Removed `socket.disconnect()` from the cleanup function
+- Left a `// TODO: wire real socket events once War Room backend lands` comment above the `setInterval` so the intent is clear when the backend arrives
+
+**Post-merge update:** Accepted upstream's import path change (`@unvibe/types` instead of `@/lib/mock-data/types`). The socket removal and TODO are preserved.
+
+---
+
+### 6. Hardcoded gradient hex values in ThemeProvider
+
+**Commit:** `f56b01d` | **Files:** `apps/web/src/app/globals.css`, `apps/web/src/components/app/theme-provider.tsx`
+
+**Problem:** `ThemeProvider` contained raw hex values inline:
+- Dark: `radial-gradient(125% 125% at 50% 100%, #000000 40%, #010133 100%)`
+- Light: `radial-gradient(125% 125% at 50% 90%, #ffffff 40%, #ec4899 100%)`
+
+These weren't tied to the design token system. If the palette changed, they'd need manual updates.
+
+**Fix:**
+- Added `--gradient-radial` to `:root` (light) and `.dark` (dark) in `globals.css`, alongside the existing CSS custom properties
+- Simplified `ThemeProvider` to: `style={{ background: "var(--gradient-radial)" }}`
+- The CSS variable resolves automatically based on the `.dark` class on `<html>` — no conditional logic needed in the component
+
+---
+
+## Merge Details
+
+**Commit:** `1269c6f`
+
+Merged `upstream/main` into `feat/frontend-app-shell` with **7 file conflicts**, all resolved manually:
+
+| File | Resolution strategy |
+|------|-------------------|
+| `page.tsx` (module) | Keep our async Server wrapper, update inner component with upstream's tRPC |
+| `signin/page.tsx` | Accept upstream (real auth form supersedes our mock fix) |
+| `signup/page.tsx` | Accept upstream (real auth form supersedes our mock fix) |
+| `layout.tsx` | Keep our flash-fix version (upstream still had old hardcoded `className="dark"`) |
+| `theme-provider.tsx` | Keep our CSS-variable version (upstream still had old inline hexes) |
+| `code-editor.tsx` | Merge: upstream multiline signature + our darkMode logic |
+| `war-room-live.tsx` | Merge: upstream import path + our socket cleanup |
+
+Also fixed 4 pre-existing build blockers found during merge verification (all from upstream's new code):
+- Installed `dotenv` dependency (missing in `next.config.mjs`)
+- Installed `bcryptjs` + `@types/bcryptjs` for upstream's new auth router (`api`)
+- Ran `prisma generate` (stale client after schema changes)
+- Built `@unvibe/types` (unbuilt after type additions)
+

+
+## Verification
+
+```bash
+pnpm lint     # ✅ No ESLint warnings or errors
+pnpm build    # ✅ Compiled successfully, all 13 pages generated
+```

+The merge commit `1269c6f` shows how each conflict was resolved.
+
+The latest merge commit `5a7d39d` brings in upstream/main (71 commits) and adds the post-review UX improvements below.
+
+---
+
+## UI & UX Improvements (Post-Review)
+
+### Loading State / Skeleton
+
+- Added `SkeletonLoader` component (`apps/web/src/components/ui/skeleton-loader.tsx`)
+  - Page-level variants: `dashboard`, `tracks`, `war-room`, `module`
+  - Wraps the upstream skeleton primitives (`Skeleton`, `SkeletonCard`, `SkeletonStatCard`, `SkeletonList`) from `@/components/app/skeleton`
+  - Proper `role="status"` and `aria-label` for accessibility
+  - `sr-only` "Loading..." text for screen readers
+- Replaced `LoadingPanel` with `SkeletonLoader` in:
+  - `apps/web/src/app/app/tracks/page.tsx` → `variant="tracks"` (3-column card grid skeleton)
+  - `apps/web/src/app/app/tracks/[trackId]/modules/[moduleId]/module-page-content.tsx` → `variant="module"` (player layout skeleton)
+- Upstream-merged `loading.tsx` files cover the remaining pages via Next.js Suspense:
+  - `dashboard/loading.tsx` → stat cards + content grid skeleton
+  - `war-room/loading.tsx` → message area + leaderboard skeleton
+  - `blindspot-map/loading.tsx`, `profile/loading.tsx`, module `loading.tsx`
+- Visible during initial page load (tested on Slow 3G via DevTools throttle)
+
+### Custom Scrollbar
+
+- Added themed scrollbar CSS to `apps/web/src/app/globals.css` (outside `@layer` — required for `::-webkit-scrollbar` to work)
+- Light mode: neutral gray track (`#f1f1f1`) + medium thumb (`#888`)
+- Dark mode: `.dark ::-webkit-scrollbar-*` selectors auto-switch when `ThemeController` toggles the `.dark` class on `<html>`
+- Hover state for both modes; no green, blue, or purple per brand constraint
+- Smooth color transitions with theme toggle
+
+### Logo & Favicon
+
+- Generated techy geometric "UV" lettermark logo (`apps/web/public/logo.png`, 512×512)
+  - Color palette: coral/rose (`#e05c5c`) + teal (`#2dd4bf`) — no green, blue, or purple
+  - Hexagonal grid background pattern, circuit trace accents
+  - Transparent background PNG
+- Favicon copied to `apps/web/public/favicon.ico` (32×32)
+- Updated `apps/web/src/app/layout.tsx` `metadata.icons`:
+  ```tsx
+  icons: {
+    icon: "/favicon.ico",
+    apple: "/logo.png",
+  }
+  ```
+  Uses Next.js App Router metadata API (cleaner than raw `<link>` tags, no hydration warnings)
+- Visible in browser tabs and bookmarks; Apple touch icon for mobile home screen add
