Subject: [PATCH] feat: integrate PPC Coach companion + add /learn docs section
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Coaches:
- public/ppc-coach.html: full 12-module teaching companion (115KB, self-contained)
- app/coach/page.tsx: Next.js shell with sandboxed iframe + back nav

Learn section (app/learn/):
- layout.tsx + Sidebar + PrintButton: shared shell with sticky header,
  sidebar nav, and Ctrl+P print button on every page
- page.tsx: hub with 4 entry cards + "How to use this site" + "What is PPC Coach?"
- features/page.tsx: 9 feature docs inline, each with what/when/steps/
  pro tips/mistakes/related
- guide/page.tsx: 6-phase student guide (Week 0 → After) with hours,
  goals, what-to-do, exit-checks, when-you're-stuck, graduation checklist
- handouts/page.tsx: 8 printable cheat sheets (ACOS, match types,
  bids & budgets, search terms, launch plan, VA cadence,
  troubleshooting, report format)
- downloads/page.tsx: file table with print-to-PDF instructions and
  offline notes

Downloadables (public/downloads/):
- va-starter-kit.md: 30-day onboarding checklist
- 4-week-launch-plan.md: printable launch plan
- ppc-coach-offline.html: full app, standalone
- ppc-coach-source.zip: 35KB archive for email/drive sharing

Landing page (app/page.tsx):
- 4-card grid: AdConsole Simulator · PPC Coach · Learn & Docs · React port
- Both static files now auto-show size + last-modified

Verified: type-check clean, lint clean (0 warnings), next build
succeeds with / and /coach and /learn/* prerendered, all 10 dev
routes return 200.

+# 4-Week New Product Launch Plan
+
+A one-page plan you can hand to a client or pin above your monitor.
+
+## Week 1 — Learn
+
+- [ ] One Auto campaign only.
+- [ ] Small daily budget (start $10–$20/day for a new product).
+- [ ] Modest bids (start at Amazon’s suggested bid).
+- [ ] Goal: **collect data, not profit.**
+- [ ] Read the search term report daily. Don’t act yet.
+
+## Week 2 — Control
+
+- [ ] Launch a manual **Exact** campaign with 3–5 long-tail keywords.
+- [ ] Pull the top 3 search terms from Week 1&apos;s Auto report. Use them as seeds.
+- [ ] Keep Auto running but reduce its budget share.
+- [ ] Bids: start at the Auto average CPC, give or take 10%.
+- [ ] Goal: **get the first sales from intentional keywords.**
+
+## Week 3 — Clean
+
+- [ ] First negatives pass.
+  - Search terms with 5+ clicks and 0 sales, clearly irrelevant.
+  - Wrong material, wrong use, wholesale, free, used, etc.
+- [ ] Tighten Exact match: add phrase-match variants of proven winners.
+- [ ] Audit the listing. Are image, title, bullets, and reviews good enough to convert the traffic you&apos;re paying for?
+- [ ] Goal: **stop the bleed, sharpen the focus.**
+
+## Week 4 — Scale (carefully)
+
+- [ ] Bump the budget on the Exact campaign by 10–20%.
+- [ ] Raise bids on proven winners by 10–15%, one at a time.
+- [ ] Add a Product Targeting campaign against close competitors.
+- [ ] Generate a weekly report. Compare against the launch forecast.
+- [ ] Goal: **scale only what has earned the right to be scaled.**

+| When | What |
+| --- | --- |
+| Daily (5 min) | Spend, stock, paused campaigns, alerts |
+| Weekly (1 hr) | Search term harvest, negatives, bid review, report |
+| Monthly (2 hr) | Structure, top keywords, listing audit, cleanup |
+
+## Stop-loss rules
+
+- If ACOS is **2× margin** for 7 days, pause the campaign and review.
+- If CTR is **under 0.3%** for 7 days, fix the hook (image, price, title).
+- If conversion is **under 5%** for 14 days, fix the listing before spending more.
+- If the listing loses the **Buy Box**, pause ads until it&apos;s back.
+
+## Done-when checklist
+
+By the end of week 4, you should be able to:
+
+- [ ] Show a week-1-to-week-4 trend chart with rising sales and falling ACOS.
+- [ ] List your top 5 keywords and the bid for each.
+- [ ] List your top 5 negative keywords and why each was added.
+- [ ] State the campaign&apos;s current break-even ACOS and whether it&apos;s profitable.
+- [ ] Propose the next 2 changes you would make in week 5.

+# VA Starter Kit — Amazon PPC
+
+A copy-paste checklist for your first 30 days on a real Amazon PPC account.
+
+## Day 1: ask your manager these questions
+
+- [ ] What is our account-level profit margin? (This is your break-even ACOS.)
+- [ ] Which products am I responsible for, and which are off-limits?
+- [ ] Who approves budget changes? Who approves new campaign structure?
+- [ ] What is the daily / weekly / monthly reporting cadence?
+- [ ] Where is the change log? (If there isn&apos;t one, start one today.)
+- [ ] Which account-level tools am I allowed to use? (Search-term reports, bulk sheets, etc.)
+- [ ] Is there a Slack channel or email thread for PPC questions?
+- [ ] What does “success” look like 30, 60, 90 days from now?
+
+## Week 1: read and shadow
+
+- [ ] Read every lesson in the **PPC Coach** course.
+- [ ] Pass all 12 module quizzes at 70%+.
+- [ ] Take the Final Exam at least once (aim for 85%+ by month-end).
+- [ ] Run the **Search Term Trainer** three times. Beat your own best.
+- [ ] Run the **Campaign Builder** for the three practice products. Score 70+ on each.
+- [ ] Generate at least one practice weekly report in the **Report Builder**.
+- [ ] Ask the AI Coach at least 3 questions.
+- [ ] Shadow a senior VA on a real account for 2 hours.
+
+## Week 2–3: small safe moves
+
+- [ ] On a sandbox or a low-budget test product, add 5 negative keywords.
+- [ ] Make 1 bid change. Log it. Wait a week. Compare.
+- [ ] Download a real search term report. Mark 3 winners, 3 wasters. Propose actions.
+- [ ] Run a full weekly report on a real account. Send it to your manager for review.
+
+## Week 4: solo with supervision
+
+- [ ] You can explain ACOS, ROAS, TACoS, and break-even in your own words.
+- [ ] You can run a weekly search-term harvest without help.
+- [ ] You have a change log with at least 10 entries, all dated and explained.
+- [ ] You have asked at least 5 questions (and remember the answers).
+- [ ] You can spot a low-CTR, high-ACOS, or no-impression problem and propose a fix.
+
+## Daily 5-minute check
+
+```
+[ ] Spend on track vs forecast
+[ ] No new paused campaigns
+[ ] No stock alerts
+[ ] No budget left at 0
+[ ] No review of "did something just change?"
+```
+
+## Weekly 1-hour routine
+
+| Day | Task |
+| --- | --- |
+| Monday | Spend, budgets, urgent alerts |
+| Tuesday | Search term review |
+| Wednesday | Negatives + promote winners |
+| Thursday | Bid and ACOS review |
+| Friday | Simple report |
+
+## Permission ladder (from Module 11)
+
+| Task | You alone | Needs approval |
+| --- | --- | --- |
+| Download and clean reports | ✅ | |
+| Add negatives from rules | ✅ | |
+| Small bid moves (±20%) | ✅ | |
+| Promote winners to Exact | ✅ | |
+| Budget changes | | ✅ |
+| New campaign structure | | ✅ |
+| Pausing a whole campaign | | ✅ |
+| Strategy shifts | | ✅ |
+
+## When in doubt
+
+1. **Stock, price, reviews, competitors** — in that order.
+2. **One change at a time.** Then wait a week.
+3. **Log everything.** Memory lies.
+4. **Ask early, ask often.** A question costs a minute; a mistake costs a client.
