Subject: [PATCH 1/8] fix: await params in ModulePage via Server Component
 wrapper (Next.js 15 compat)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ModulePage was a Client Component destructuring params synchronously. In Next.js
15, params is a Promise. Since React 18 doesn't have use(), wrap the client
logic in a thin async Server Component that awaits params and passes them as
plain props to the inner Client Component.

No other files in the app/ tree destructure params or searchParams — this was
the only instance.

Subject: [PATCH 2/8] fix: prevent dark-mode flash on light-mode load

Remove hardcoded className="dark" from <html>. Add blocking inline script
that reads localStorage("unvibe-theme") and sets the class before first
paint, matching the Zustand store's persistence strategy. Add
suppressHydrationWarning to <html> to silence the false-positive mismatch
warning since the DOM is intentionally mutated before hydration.

MIME-Version: 1.0

Socket connect/disconnect was called but no socket events were listened
to — only a setInterval drove mock messages. Remove the socket calls and
unused getSocket import. Leave a TODO to wire real socket events when the
War Room backend lands.

+## 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)

+
+---
+
+## 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

Subject: [PATCH 8/8] fix(ux): prevent hydration mismatch in ThemeController
 SVG icons

ThemeController conditionally renders Moon vs Sun based on Zustand
darkMode state. Zustand only initializes on the client, so the server
always renders the default while the client may render a different icon.
This caused a React hydration error:
  'Expected server HTML to contain a matching <circle> in <svg>'

Fix: add a mounted guard that defers the conditional icon to after
first useEffect, rendering Sun as a neutral SSR placeholder in the
meantime. Both server and client agree on Sun until mount; then the
client silently swaps to the correct icon.
