It looks like the conversational preparation component is hidden if the user ...

Let me check if there's an existing login-required pattern used elsewhere in the codebase.

Let me look at how text-submission and activity-stages-preview handle the login prompt — those seem like good patterns to follow.

Good, I can see the existing patterns. The TextSubmission and MediaSubmission components use a simple box with a login link. I'll match the style of the PreparationChatCard but show a login prompt instead. Let me update the PreparationChat component.

Now let me verify the final file looks correct.

I notice I imported LogIn but didn't use it. Let me clean that up.

Done. Now instead of returning null when the user isn't logged in, the PreparationChat component renders a card matching the same visual style (accent border, BookOpen icon, same spacing) with a "Log in" link pointing to /login. The text reads "Log in to prepare for this discussion." — consistent with how TextSubmission and MediaSubmission handle unauthenticated users.

Let me check how the login page handles returnTo and how other components pass it.

The pattern is /login?returnTo=<path>. But the PreparationChat component is embedded in MDX pages and doesn't know which page it's on. Let me check how to get the current URL in a server component — I'll need to use the headers() to get the path.

In a server component there's no built-in way to get the current page path. The simplest approach is a small client component that uses usePathname(). Let me add that.

Now create the client component:

Let me verify the parent file looks clean:

Done. The login prompt is now a client component (preparation-chat-login.tsx) that uses usePathname() to build the login link as /login?returnTo=<current-page>, so after logging in the student gets sent right back to the meeting page they were on.

Let me check recent changes to sidenote-related code.

Both sidenote.tsx and sidenote-ref.tsx changed recently. Let me look at the diffs and the current state.

Found it. The Prettier formatting commit (616d8c0) removed the leading spaces in the class name concatenation. Instead of sidenote-margin sidenote-margin-active (two classes), it now produces sidenote-marginsidenote-margin-active (one invalid class).

The Prettier commit (616d8c0) changed " sidenote-margin-active" to "sidenote-margin-active", dropping the leading space that separates the CSS classes. Without that space, the active/inactive modifier classes were getting concatenated onto the base class (e.g. sidenote-marginsidenote-margin-active), so none of the CSS rules matched and the hover behavior broke. Fixed in both sidenote-ref.tsx and sidenote.tsx.

Good point. Let me check what's available for class name joining.

The project has a cn utility. Let me refactor both files to use it.

Now both files use cn() from the project's existing utility, which handles class joining properly and is Prettier-safe.

Now let me specifically look for the vulnerable pattern — ternary expressions inside template literals where the space is inside the string value.

Those are text content, not class names — they're safe. All the template-literal className patterns I found use ${variable} where the space is outside the interpolation (like `foo ${bar}`), which Prettier won't break.

No other vulnerable instances found. The two sidenote files were the only ones using the ${condition ? " class" : ""} pattern that Prettier can break.

Sounds good — the cn() approach is Prettier-safe so it should survive cleanly this time.

Great, everything should be solid now. To recap the changes:

1. Preparation chat login prompt — new preparation-chat-login.tsx client component that shows a "Log in to prepare for this discussion" box with a returnTo link back to the current page, instead of hiding the component entirely.

2. Sidenote class name fix — refactored both sidenote.tsx and sidenote-ref.tsx to use cn() for class name joining, fixing the Prettier-induced bug where class names were getting concatenated without spaces.

Let me check the current git state.

I can see:

1. Untracked file: apps/web/components/mdx/preparation-chat-login.tsx (new file we created)
2. Modified files:
   • 3 actual code changes: preparation-chat.tsx, sidenote-ref.tsx, sidenote.tsx
   • Many package.json version bumps (2026.2.7 → 2026.2.8)
   • bun.lock (glob dependency update 13.0.0 → 13.0.1)

Let me check the code changes for any debugging statements:

No debugging statements found. The changes look clean. Now I'll present the commit plan:

Commit Plan

I found the following changes:

Code changes (2 logical groups):

1. Preparation chat login prompt — Show login box instead of hiding component when not authenticated

   • New file: preparation-chat-login.tsx
   • Modified: preparation-chat.tsx

2. Sidenote className fix — Use cn() utility to prevent Prettier from breaking class names

   • Modified: sidenote-ref.tsx, sidenote.tsx

Dependency updates: 3. Version bump and glob update — All package.json files (2026.2.7 → 2026.2.8) and glob (13.0.0 → 13.0.1)

Proposed commits:

1. Show login prompt for unauthenticated preparation chat users
2. Fix sidenote class names to be Prettier-safe using cn()
3. Bump version to 2026.2.8 and update glob to 13.0.1

Would you like me to:

• A — Proceed with these 3 commits
• B — Combine into fewer commits
• C — Let you take over from here
• D — Abort

All three commits are in, working tree is clean.

Yes — both the reading page and the preparation chat only check for authentication (a valid session), not for any specific role or enrollment status. Any logged-in user can access them:

• Reading page ([semester]/readings/[slug]/page.tsx:61): redirects to login if no session, but no role check after that
• Preparation chat page (preparations/[slug]/[sessionId]/page.tsx:49): same — login required, no role gate
• Preparation API routes: only use authMiddleware, no role/enrollment checks

So anyone who can log in (including non-enrolled users) can view the McLuhan reading and start a preparation discussion.

Done. Added a note after the existing instructions letting students know it's device-free — no laptops needed, phones away.

Clean, straightforward change — just adding the device-free notice to the Biondi meeting page. No debugging statements or issues.

Done! Committed the device-free notice for the Biondi meeting.
