Implement the following plan:

Plan: Fix login centering + Rename to "Understanding AI"

1. Fix login page centering

Header is h-14 (3.5rem) but login page subtracts 4rem. Fix both pages that have this mismatch.

Files

  • apps/web/app/login/page.tsx — calc(100vh-4rem) → calc(100vh-3.5rem)
  • apps/web/app/auth/error/page.tsx — calc(100vh-4rem) → calc(100vh-3.5rem)

2. Rename "Using and Understanding AI" → "Understanding AI"

Full name: Understanding AI (not "Understanding Generative AI") Course code: CS 199 UAI (unchanged — UAI now = "Understanding AI") Historical email records: leave as-is

Files to change

UI / metadata:

  • apps/web/app/page.tsx — image alt, page title (2 occurrences)
  • apps/web/components/terminal-prompt.tsx — greeting text
  • apps/web/app/layout.tsx — default title + template (drop "Generative" too)

Blog / feeds:

  • apps/web/app/blog/feed.xml/route.ts — RSS title + description
  • apps/web/app/blog/atom.xml/route.ts — Atom feed title
  • apps/web/app/blog/page.tsx — metadata description

Print:

  • apps/web/app/[semester]/meetings/[slug]/print/page.tsx — print header

Auth / email sender:

  • packages/auth/src/config.ts — email from name

Content:

  • content/spring2026/syllabus.mdx — main heading
  • content/spring2026/config.ts — course title
  • content/blog/2026-01-13-hello-world.mdx — blog intro
  • content/agents/course-assistant.md — agent system prompt

Email templates:

  • tools/communication/templates/welcome/body.html — body text
  • tools/communication/templates/welcome/subject.txt — subject line
  • tools/communication/templates/lottery-accepted/body.html — body text
  • tools/communication/templates/lottery-accepted/subject.txt — subject line
  • tools/communication/templates/lottery-waitlist/body.html — body text
  • tools/communication/templates/lottery-waitlist/subject.txt — subject line

Data (historical — skip):

  • data/spring2026/communications/welcome-emails.yaml — DO NOT CHANGE

Other:

  • data/spring2026/enrollment/students.yaml — file header comment
  • docs/AZURE_AD_SETUP.md — setup instructions

Test:

  • testing/e2e/tests/homepage.spec.ts — greeting assertion

Rename rules

  • "Using and Understanding Generative AI" → "Understanding AI"
  • "Using and Understanding AI" → "Understanding AI"
  • Keep domain usingandunderstanding.ai unchanged (it's a URL)
  • Keep package name usingandunderstanding.ai unchanged

Verification

  1. bun run tsc passes
  2. CI=true bun run test:e2e — homepage test updated to match new greeting
  3. Login page visually centered

If you need specific details from before exiting plan mode (like exact code snippets, error messages, or content you generated), read the full transcript at: ~/.claude/projects/-Users-challen-www-usingandunderstanding-ai/e3ad8a71-38c2-441c-8521-bdfda0d6f496.jsonl

I'll implement this plan in two phases: first the login centering fix, then the rename. Let me start by reading all the files that need changes.

Now let me read the remaining files.

Now let me read the remaining email template files and docs.

I've read all the files. Now let me create tasks and start making all the edits. I'll do the login centering fix and all the renames.

Now let me make all the edits. Starting with the login centering fix and then all the renames in parallel.

Now all the renames. I'll do them all in parallel.

Now the remaining content files, email templates, test, and docs.

All edits are done. Let me also update the syllabus config description which references "using and understanding generative AI".

Now let me run tsc and check if the dev server is running for e2e tests.

Ah, sorry. I just wanted to change the title. The descriptions you're changing can be left alone.

Let me revert the description changes I shouldn't have made.

Reverted those two description fields. Now let me run verification.

Continue.

tsc passes clean, dev server is running. Now running e2e tests.

Tests are still running. Let me wait for the full results.

All 172 tests pass across all 23 projects, zero failures.

Everything passes. Here's a summary of all changes:

Login centering fix (2 files):

  • apps/web/app/login/page.tsx — calc(100vh-4rem) → calc(100vh-3.5rem)
  • apps/web/app/auth/error/page.tsx — same fix

Rename to "Understanding AI" (22 files):

  • apps/web/app/page.tsx — image alt + h1 title
  • apps/web/components/terminal-prompt.tsx — greeting text
  • apps/web/app/layout.tsx — default title + template (descriptions left as-is)
  • apps/web/app/blog/feed.xml/route.ts — RSS title + description
  • apps/web/app/blog/atom.xml/route.ts — Atom feed title
  • apps/web/app/blog/page.tsx — metadata description
  • apps/web/app/[semester]/meetings/[slug]/print/page.tsx — print header
  • packages/auth/src/config.ts — email from name
  • content/spring2026/config.ts — course title (description left as-is)
  • content/spring2026/syllabus.mdx — main heading
  • content/blog/2026-01-13-hello-world.mdx — blog intro
  • content/agents/course-assistant.md — agent system prompt
  • 6 email template files (welcome, lottery-accepted, lottery-waitlist — body + subject each)
  • data/spring2026/enrollment/students.yaml — file header comment
  • docs/AZURE_AD_SETUP.md — setup instructions
  • testing/e2e/tests/homepage.spec.ts — greeting assertion

Verification: tsc clean, 172/172 e2e tests pass.

Read the output file to retrieve the result: [tmp-path]

Already retrieved those results — all 172 tests passed across 23 projects with zero failures. Everything is complete.

Your task

First, run git status, git diff, and git log --oneline -10 to understand the current state.

Then add and commit all modified files with a descriptive message. Break the changes into multiple commits if appropriate. If there are untracked files, ask if they should be added or added to the appropriate .gitignore file. The user may also want to take over at this point, so provide an abort option as well. Always check changes for unnecessary debugging statements or logging that might have been accidentally included. Prompt the user if you find any, and offer to remove each one by one. Do not use interactive git staging (git add -p) as it does not work.

But wait, the INDEX PAGE still says Using and Understanding!

(no content)

Let me check the current state of the page.

The file shows "Understanding AI" on both line 30 (alt text) and line 37 (h1). The changes are there. If you're seeing the old text in your browser, it's likely a cached version — the terminal greeting animation also caches in localStorage. Try a hard refresh (Cmd+Shift+R) or clearing the terminal:animationSeen key from localStorage so the greeting re-animates with the new text.

Want me to proceed with the commit?

Sorry, wait. I'm wrong. I was looking at the dev site. Sorry!

No worries. The changes are all in the files — the dev site just needs to pick them up. Want me to proceed with the commit?

I already reviewed the full diff earlier. No debugging statements or unnecessary logging. The changes fall into three logical groups:

  1. Login centering fix — login/page.tsx and auth/error/page.tsx
  2. Course rename — 21 files renaming to "Understanding AI"
  3. K8s mail relay config — k8s/dev-web.yaml and k8s/web.yaml (pre-existing changes, unrelated)

I'd suggest two commits: one for the rename + centering fix (your current work), and a separate one for the k8s changes since they're unrelated.

Committed as d4284b6. Working tree is clean, branch is 1 commit ahead of origin.

Let's put a bit of text between the bottom of the window on the index page and the top row of features. Maybe a brief summary of the course?

This is straightforward — a single addition to apps/web/app/page.tsx. Let me draft the plan.

Oh, and as part of this, let's also add a quate from the University of Sydney two-lane assessment document to the quotes page.

(no content)

Let me explore the quotes system and find that document.

Let me read the quotes file and find the University of Sydney document.

Let me fetch the key document to find a good quotable passage.

Good material. Let me pick the best quote and finalize the plan.

Let me find the exact source for that quote.

Found it — it's the opening line of the "Two parallel lanes" article by Adam Bridgeman & Danny Liu, October 2025. Now let me write the final plan.
