Landing Page Refactor Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Replace all marketing home components with the UI from texpixel-landing.html, preserving exact visual fidelity while integrating with React Router, AuthContext, and existing app infrastructure.

Architecture: Extract the reference HTML's <style> block into a scoped landing.css (imported only in MarketingLayout), convert each HTML section into a focused React component, and convert the reference's <script> behaviors into useEffect hooks and a shared useScrollReveal hook.

Tech Stack: React 18, TypeScript, React Router v6, Tailwind CSS (workspace only), custom CSS (marketing only), useAuth / useLanguage contexts.

Spec: docs/superpowers/specs/2026-03-26-landing-refactor-design.md Reference: texpixel-landing.html (lines 10-1593 = CSS, lines 1602-2183 = HTML, lines 2185-2289 = JS)

---

Task 1: Add Fonts to index.html

Files:

• Modify: index.html:15

• Step 1: Add Lora and JetBrains Mono to the Google Fonts link

Replace the existing fonts line (line 15) in index.html:

<link href="https://fonts.googleapis.com/css2?family=Plus+Jakarta+Sans:wght@500;600;700;800&family=DM+Sans:ital,wght@0,400;0,500;0,600;1,400&display=swap" rel="stylesheet" />

With:

<link href="https://fonts.googleapis.com/css2?family=Plus+Jakarta+Sans:wght@500;600;700;800&family=DM+Sans:ital,opsz,wght@0,9..40,300;0,9..40,400;0,9..40,500;0,9..40,600;1,9..40,300&family=Lora:ital,wght@0,400;0,600;0,700;1,400&family=JetBrains+Mono:wght@400;500&display=swap" rel="stylesheet" />

• Step 2: Verify build still passes

npm run typecheck

Expected: no errors

• Step 3: Commit

git add index.html
git commit -m "feat: add Lora and JetBrains Mono fonts for landing page"

---

Task 2: Extract Landing CSS

Files:

• Create: src/styles/landing.css

• Step 1: Create the styles directory and file

mkdir -p src/styles

• Step 2: Copy the CSS from the reference and apply scoping

Copy lines 10–1593 from texpixel-landing.html (everything inside the <style> tag) into src/styles/landing.css.

Then apply these transformations to prevent workspace bleed:

Original selector	Replace with
body {	.marketing-page {
body::before {	.marketing-page::before {
html { scroll-behavior: smooth; }	Remove this line (already in index.css via Tailwind base)
section { position: relative; z-index: 1; }	.marketing-page section { position: relative; z-index: 1; }
nav {	.marketing-page nav {
footer { (the footer padding rule)	.marketing-page footer {

Leave :root { ... } untouched — the variable names (--primary, --bg, etc.) don't conflict with the workspace's variables (--color-primary, --color-bg).

All class-based selectors (.hero, .btn, .product-card, etc.) need no change — they are unique enough to not affect the workspace.

At the very end of the file, add the scroll reveal animation rule used by JS:

.reveal {
  opacity: 0;
  transform: translateY(24px);
  transition: opacity 0.55s ease, transform 0.55s ease;
}
.reveal.visible {
  opacity: 1;
  transform: translateY(0);
}
.reveal-delay-1 { transition-delay: 0.10s; }
.reveal-delay-2 { transition-delay: 0.20s; }
.reveal-delay-3 { transition-delay: 0.30s; }

• Step 3: Verify the file exists

ls src/styles/landing.css

Expected: file listed

• Step 4: Commit

git add src/styles/landing.css
git commit -m "feat: extract landing page CSS from reference HTML"

---

Task 3: Update MarketingLayout

Files:

• Modify: src/components/layout/MarketingLayout.tsx

• Step 1: Replace MarketingLayout.tsx

import { Outlet } from 'react-router-dom';
import MarketingNavbar from './MarketingNavbar';
import Footer from './Footer';
import '../../styles/landing.css';

export default function MarketingLayout() {
  return (
    <div className="marketing-page">
      <div className="glow-blob glow-blob-1" />
      <div className="glow-blob glow-blob-2" />
      <div className="glow-blob glow-blob-3" />
      <MarketingNavbar />
      <main>
        <Outlet />
      </main>
      <Footer />
    </div>
  );
}

• Step 2: Verify typecheck passes

npm run typecheck

Expected: no errors

• Step 3: Commit

git add src/components/layout/MarketingLayout.tsx
git commit -m "feat: wire landing.css into MarketingLayout with .marketing-page scope"

---

Task 4: Create useScrollReveal Hook

Files:

• Create: src/hooks/useScrollReveal.ts

• Step 1: Create hooks directory and hook file

// src/hooks/useScrollReveal.ts
import { useEffect } from 'react';

export function useScrollReveal() {
  useEffect(() => {
    const observer = new IntersectionObserver(
      (entries) => {
        entries.forEach((e) => {
          if (e.isIntersecting) {
            e.target.classList.add('visible');
            observer.unobserve(e.target);
          }
        });
      },
      { threshold: 0.12, rootMargin: '0px 0px -40px 0px' }
    );

    document.querySelectorAll('.reveal').forEach((el) => observer.observe(el));

    return () => observer.disconnect();
  }, []);
}

• Step 2: Verify typecheck

npm run typecheck

Expected: no errors

• Step 3: Commit

git add src/hooks/useScrollReveal.ts
git commit -m "feat: add useScrollReveal hook for intersection-based fade-in"

Task 14: Update HomePage + Delete Old Components + Clean Translations

Files:

• Modify: src/pages/HomePage.tsx

• Modify: src/lib/translations.ts

• Step 2: Remove dead contact keys from translations.ts

In src/lib/translations.ts:

• Remove contact: 'Contact', from the en.marketing.nav block (around line 115)

• Remove contact: '联系我们', from the zh.marketing.nav block (around line 297)

• Remove the entire en.marketing.contact block (the object starting with contact: { title: around line 165–175)

• Remove the entire zh.marketing.contact block (equivalent block in the zh section)

• Step 3: Delete old components

rm src/components/home/HowItWorksSection.tsx
rm src/components/home/ContactSection.tsx

• Step 4: Verify typecheck and build

npm run typecheck && npm run build

Expected: no TypeScript errors, build succeeds

• Step 5: Commit

git add src/pages/HomePage.tsx src/lib/translations.ts
git rm src/components/home/HowItWorksSection.tsx src/components/home/ContactSection.tsx
git commit -m "feat: wire all landing sections in HomePage, remove obsolete components"

Task 15: Verify CSS Scoping Does Not Break Workspace

Files:

• No code changes — verification only

• Step 1: Run the dev server and navigate to /app

npm run dev

Open http://localhost:5173/app — verify:

• The workspace AppLayout and WorkspacePage render correctly

• No .marketing-page CSS rules leak (no warm beige background, no grid overlay on the workspace)

• Step 2: Navigate to / (home)

Open http://localhost:5173/ — verify:

• Background matches reference (#FFFBF7 warm cream with grid pattern)

• All three glow blobs visible as ambient background

• Navbar, Hero, all sections, and Footer match the reference HTML visually

• Step 3: Run full build

npm run build

Expected: success with no errors

• Step 4: Final commit

git add -A
git commit -m "chore: final verification — landing refactor complete"
