Prompt

Build a single React + TypeScript + Tailwind CSS v3 component called `FreedomSection`. It uses `hls.js` for HLS video streaming and `useEffect` / `useRef` from React. No external icon libraries — all icons are inline SVG or `<img>` tags. Fully mobile-responsive. No hover states.

---

## Global font

Register **"Mazzard H"** in `index.css` and apply it globally:

```css
@font-face {
  font-family: 'Mazzard H';
  font-weight: 400;
  font-style: normal;
  src: url('https://db.onlinewebfonts.com/t/eb5b5ee332420add9a40ee988cb6ac37.woff2') format('woff2'),
       url('https://db.onlinewebfonts.com/t/eb5b5ee332420add9a40ee988cb6ac37.woff') format('woff'),
       url('https://db.onlinewebfonts.com/t/eb5b5ee332420add9a40ee988cb6ac37.ttf') format('truetype');
}
@font-face {
  font-family: 'Mazzard H';
  font-weight: 500;
  font-style: normal;
  src: url('https://db.onlinewebfonts.com/t/875fffdfa62169a0f131e90f37f1faf4.woff2') format('woff2'),
       url('https://db.onlinewebfonts.com/t/875fffdfa62169a0f131e90f37f1faf4.woff') format('woff'),
       url('https://db.onlinewebfonts.com/t/875fffdfa62169a0f131e90f37f1faf4.ttf') format('truetype');
}

@tailwind base;
@tailwind components;
@tailwind utilities;

@layer base {
  html, body, * { font-family: 'Mazzard H', sans-serif; }
}
```

---

## Dependencies

`hls.js` must be installed: `npm install hls.js`. It is imported as `import Hls from 'hls.js'`.

---

## File: `src/components/FreedomSection.tsx`

### Constants (top of file)

```ts
const HLS_SRC = 'https://stream.mux.com/bnYL6x5cAX6WiJv2pOKpITehZd3NVdXpj3ylJFpX5Lk.m3u8';

const CROSS_ICON = 'https://cdn.prod.website-files.com/6720dd1ab6df0da205830ab1/686cc0f520a992816d8b15dc_bullet-list-cross.svg';
const CHECK_ICON = 'https://cdn.prod.website-files.com/6720dd1ab6df0da205830ab1/686cc068490683bbb3377d04_bullet-list.svg';

const negatives = [
  'Reactive firefighting when foundational issues surface too late',
  'Bloated coordination overhead drains bandwidth from core teams',
  "Constant re-verification because source data can't be trusted",
  'Fragmented vendor relations produce mismatched deliverables',
  'Scattered specs and decisions buried across siloed systems',
];

const positives = [
  'Layered dependency maps eliminate costly surprises at every phase',
  'Streamlined team handoffs deliver production-ready outcomes fast',
  'Live validation loops keep requirements locked across all stages',
  'Unified vendor management through a single accountable contact',
  'Centralized context and clear records accelerate every decision',
];
```

---

### `HlsVideo` sub-component (defined above `FreedomSection`, not exported)

```ts
function HlsVideo() {
  const videoRef = useRef<HTMLVideoElement>(null);

  useEffect(() => {
    const video = videoRef.current;
    if (!video) return;

    if (Hls.isSupported()) {
      const hls = new Hls({
        startLevel: -1,
        capLevelToPlayerSize: false,
        maxMaxBufferLength: 60,
        enableWorker: true,
      });
      hls.loadSource(HLS_SRC);
      hls.attachMedia(video);
      hls.on(Hls.Events.MANIFEST_PARSED, () => {
        hls.currentLevel = hls.levels.length - 1;
        video.play().catch(() => {});
      });
      return () => hls.destroy();
    } else if (video.canPlayType('application/vnd.apple.mpegurl')) {
      video.src = HLS_SRC;
      video.play().catch(() => {});
    }
  }, []);

  return (
    <video
      ref={videoRef}
      autoPlay
      loop
      muted
      playsInline
      style={{
        width: '160%',
        height: '160%',
        objectFit: 'cover',
        position: 'absolute',
        top: '50%',
        left: '50%',
        transform: 'translate(-50%, -50%)',
      }}
    />
  );
}
```

The video is zoomed to `160% x 160%` and centered with `translate(-50%, -50%)` inside a circular clipping container, so it fills the circle with no letterboxing.

### `FreedomSection` component

**`<section>`** — Tailwind: `w-full flex flex-col items-center`

Inline:
```
background-color: #ffffff
padding: clamp(48px, 6vw, 80px) clamp(16px, 3vw, 40px)
gap: 36px
```

---

#### Block 1 — Header

Tailwind: `flex flex-col items-center gap-9 text-center`

**Badge pill:**

Tailwind: `flex items-center gap-2 text-lg font-medium rounded-full`

Inline: `background-color: rgb(249, 249, 249)`, `padding: 0.9vw 1.25vw`, `color: rgb(26, 11, 84)`

Contains this inline SVG (`width: 19px`, `height: 18px`, `flex-shrink: 0`, `viewBox="0 0 17 16"`, `fill="none"`, `xmlns="http://www.w3.org/2000/svg"`):

</g>
<defs>
  <clipPath id="freedom-clip">
    <rect width="16" height="16" fill="white" transform="translate(0.5)" />
  </clipPath>
</defs>
```

After the SVG: plain text **"Control"**

**`<h2>`** — Tailwind: `font-medium`

Inline: `font-size: clamp(32px, 4vw, 56px)`, `color: rgb(26, 11, 84)`, `line-height: 1.15`, `margin: 0`

Structure:
```
Stop absorbing the chaos.<br />
<span gradient>Run with confidence.</span>
```

Gradient `<span>` inline styles:
```
background-image: linear-gradient(90deg, rgb(43,167,255), rgb(202,69,255) 50%, rgb(254,136,27))
-webkit-background-clip: text
background-clip: text
-webkit-text-fill-color: transparent
color: transparent
padding-bottom: 0.3vw
display: inline-block
```

---

#### Block 2 — Three-column grid

Tailwind: `w-full flex flex-col lg:grid`

Inline:
```
grid-template-columns: 26vw 1fr 26vw
column-gap: 36px
row-gap: 24px
align-items: start
padding: 0 clamp(0px, 2.92vw, 40px)
gap: 24px
```

On mobile (`flex flex-col`): stacks vertically. On `lg:` and above: renders as 3-column grid with `gridTemplateColumns: '26vw 1fr 26vw'`.

---

##### Left column — Negatives

Tailwind: `flex flex-col`

Inline: `gap: 12px`, `font-size: clamp(13px, 1.15vw, 17px)`, `color: rgb(131, 121, 158)`

Map over `negatives`. Each card `<div>` — Tailwind: `flex flex-col`

Inline:
```
gap: 12px
padding: clamp(12px, 0.97vw, 16px) clamp(14px, 1.25vw, 20px)
border-radius: 18px
background-color: rgb(255, 255, 255)
box-shadow: 0 3px 9.1px #3f4a7e0d, 0 1px 29px #3f4a7e1a
```

Contents:
1. `<img src={CROSS_ICON} alt="" aria-hidden style={{ width: 'clamp(16px, 1.25vw, 20px)', flexShrink: 0 }} />`
2. `<div>{text}</div>` — inherits parent `color: rgb(131, 121, 158)`

---

##### Center column — Video circle

Tailwind: `flex items-center justify-center order-first lg:order-none`

Inline: `align-self: center`

On mobile, `order-first` places the video above both card columns. On `lg:`, `lg:order-none` restores it to the middle.

Inside, a circular container:
```
position: relative
border-radius: 50%
overflow: hidden
width: clamp(200px, 22vw, 400px)
height: clamp(200px, 22vw, 400px)
flex-shrink: 0
```

Inside the circle: `<HlsVideo />` (described above — the `<video>` is absolutely positioned at 160% size, centered with translate -50% -50%).

---

##### Right column — Positives

Tailwind: `flex flex-col`

Inline: `gap: 12px`, `font-size: clamp(13px, 1.15vw, 17px)`

Map over `positives`. Each card `<div>` — Tailwind: `flex flex-col`

Inline: (same shadow/padding/border-radius as negatives)
```
gap: 12px
padding: clamp(12px, 0.97vw, 16px) clamp(14px, 1.25vw, 20px)
border-radius: 18px
background-color: rgb(255, 255, 255)
box-shadow: 0 3px 9.1px #3f4a7e0d, 0 1px 29px #3f4a7e1a
```

Contents:
1. `<img src={CHECK_ICON} alt="" aria-hidden style={{ width: 'clamp(16px, 1.25vw, 20px)', flexShrink: 0 }} />`
2. `<div style={{ color: 'rgb(26, 11, 84)' }}>{text}</div>`

---

## Layout summary

- **Mobile**: flex-col — video first (order-first), then left negatives, then right positives stacked vertically
- **Desktop (lg+)**: CSS grid — left negatives | center video circle | right positives
- Section background is pure white `#ffffff`
- No animations, no hover states, no scroll effects

Reusable method

Key decisions

Check whether information hierarchy, module order, and CTA clarity all hold in the final result.

Adapt it to your subject

Extract “target result → the product name, audience, page modules, and primary button → constraints” as a reusable template for similar work.

Where it breaks

Run single-variable comparisons around module order, value proposition, and CTA placement. Record the model, cost, and failures; turn it into a Skill only after it repeats reliably.
