Build a high-converting landing page with copy, design and code

You are a conversion copywriter and front-end developer in one. Write, design and code a single landing page whose only job is to get [GOAL, e.g. demo bookings / app installs / course sign-ups].

## The offer
- Product or service: [WHAT IT IS]
- Who it is for: [TARGET CUSTOMER, their job and situation]
- Their biggest pain: [PAIN]
- The result they get: [OUTCOME, with a number if possible]
- Price or offer: [PRICE / FREE TRIAL / DISCOUNT]
- Proof we have: [testimonials, client logos, numbers, awards]
- Main objections people raise: [OBJECTIONS]
- Traffic source: [Google Ads / Facebook ads / email / organic]
- Brand colours and fonts: [DETAILS]
- Technology: [plain HTML + CSS + JS / Tailwind / React / Next.js]

## Step 1: Copy (reply with this first and wait for my approval)
Write the copy for each section, with 3 headline options for the hero:
1. Hero: headline, subheadline, primary button, a line under the button that removes risk (e.g. "No card needed"), hero image or product screenshot idea.
2. Logos or "trusted by" strip.
3. The problem, in the customer's own words.
4. The solution and how it works in 3 steps.
5. Benefits (not features): 4 to 6, each with a short heading and one sentence.
6. Social proof: testimonials with name, role and photo, plus a key number.
7. Offer and pricing with what is included and a guarantee.
8. Objection handling as an FAQ (6 to 8 questions).
9. Final call to action that repeats the main promise.
Use plain, specific words, short sentences and no hype words such as "revolutionary" or "game-changing".

## Step 2: Code (after I approve the copy)
- One responsive page, mobile first, with a sticky call-to-action button on mobile.
- The form: [FIELDS], validated, spam-protected, sending to [EMAIL / CRM / webhook URL], with a thank-you state and no page reload.
- Lighthouse 95+ on mobile: no layout shift, compressed images with width and height, system or self-hosted fonts, minimal JavaScript.
- Accessibility: semantic HTML, labels, focus states, contrast 4.5:1.
- Tracking: Google Analytics 4 and Meta Pixel events for button clicks and form submits, UTM parameters saved with each lead.
- Meta title, description, Open Graph image and FAQPage JSON-LD.
- Each section in its own clearly marked block so I can A/B test headlines.
Give the complete code for every file with its path, never shortened, and a list of what I must replace (images, keys, URLs).
