液态玻璃 CTA

Build a "CTA + Footer" section component for a React + Vite + Tailwind CSS project. This is a cinematic full-width call-to-action section with an HLS video background, centered text, two CTA buttons, and a minimal footer bar at the bottom. Black background, white text, liquid glassmorphism effects.

### FONTS (import in index.css or HTML head)

```
https://fonts.googleapis.com/css2?family=Instrument+Serif:ital@0;1&family=Barlow:wght@300;400;500;600&display=swap
```

- Headings: `Instrument Serif` italic -- Tailwind class `font-heading`
- Body: `Barlow` -- Tailwind class `font-body`

Add to `tailwind.config.ts` under `theme.extend.fontFamily`:
```js
heading: ["'Instrument Serif'", "serif"],
body: ["'Barlow'", "sans-serif"],
```

Base styles in `index.css`:
```css
body {
  font-family: 'Barlow', sans-serif;
  background: #000;
  color: #fff;
}
h1, h2, h3 {
  font-family: 'Instrument Serif', serif;
}
```

---

### LIQUID GLASS CSS (add to index.css inside `@layer components`)

```css
@layer components {
  .liquid-glass-strong {
    background: rgba(255, 255, 255, 0.01);
    background-blend-mode: luminosity;
    backdrop-filter: blur(50px);
    -webkit-backdrop-filter: blur(50px);
    border: none;
    box-shadow: 4px 4px 4px rgba(0, 0, 0, 0.05),
      inset 0 1px 1px rgba(255, 255, 255, 0.15);
    position: relative;
    overflow: hidden;
  }

  .liquid-glass-strong::before {
    content: '';
    position: absolute;
    inset: 0;
    border-radius: inherit;
    padding: 1.4px;
    background: linear-gradient(
      180deg,
      rgba(255, 255, 255, 0.5) 0%,
      rgba(255, 255, 255, 0.2) 20%,
      rgba(255, 255, 255, 0) 40%,
      rgba(255, 255, 255, 0) 60%,
      rgba(255, 255, 255, 0.2) 80%,
      rgba(255, 255, 255, 0.5) 100%
    );
    -webkit-mask: linear-gradient(#fff 0 0) content-box, linear-gradient(#fff 0 0);
    -webkit-mask-composite: xor;
    mask-composite: exclude;
    pointer-events: none;
  }
}
```

The `::before` pseudo-element uses a mask-composite trick to render a thin glowing gradient border that fades out in the middle of each side.

### DEPENDENCIES

```
npm install lucide-react hls.js
```

- `ArrowUpRight` icon from `lucide-react`
- `hls.js` for streaming the Mux HLS video

---

### HLS VIDEO URL (Mux)

```
https://stream.mux.com/8wrHPCX2dC3msyYU9ObwqNdm00u3ViXvOSHUMRYSEe5Q.m3u8
```

This is an HLS stream that requires `hls.js` to play in non-Safari browsers. Safari supports HLS natively via `<video>`.

---

### EXACT COMPONENT CODE

```tsx
import { useEffect, useRef } from "react";
import { ArrowUpRight } from "lucide-react";
import Hls from "hls.js";

const CtaFooter = () => {
  const videoRef = useRef<HTMLVideoElement>(null);

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

    const src = "https://stream.mux.com/8wrHPCX2dC3msyYU9ObwqNdm00u3ViXvOSHUMRYSEe5Q.m3u8";

    if (Hls.isSupported()) {
      const hls = new Hls();
      hls.loadSource(src);
      hls.attachMedia(video);
      return () => hls.destroy();
    } else if (video.canPlayType("application/vnd.apple.mpegurl")) {
      video.src = src;
    }
  }, []);

  return (
    <section className="relative py-32 px-6 md:px-16 lg:px-24 text-center overflow-hidden">
      {/* Background HLS Video */}
      <video

### HLS VIDEO SETUP PATTERN

The `useEffect` hook initializes `hls.js` for non-Safari browsers and falls back to native HLS for Safari:

1. Check `Hls.isSupported()` -- if true, create an `Hls` instance, load the `.m3u8` source, attach to the `<video>` element
2. If not supported but the browser can play `application/vnd.apple.mpegurl` (Safari), set `video.src` directly
3. Cleanup: `hls.destroy()` on unmount

The `<video>` element uses `autoPlay loop muted playsInline` -- all four attributes are required for autoplay to work across browsers (especially mobile).

---

### VIDEO OVERLAY FADE PATTERN

Two absolutely positioned `<div>` elements create black gradient fades at the top and bottom edges, making the video blend seamlessly into the surrounding black background:

- **Top fade**: `height: 200px`, `background: linear-gradient(to bottom, black, transparent)`, `z-[1]`, `pointer-events-none`
- **Bottom fade**: `height: 200px`, `background: linear-gradient(to top, black, transparent)`, `z-[1]`, `pointer-events-none`

Content sits at `z-10` above both the video and the fades.

---

### RESPONSIVE BEHAVIOR

| Breakpoint | Heading size | Padding | Footer layout |
|---|---|---|---|
| Mobile (default) | `text-5xl` | `px-6` | Stacked column (`flex-col`) |
| Tablet (`md:`) | `text-6xl` | `px-16` | Horizontal row (`md:flex-row`) |
| Desktop (`lg:`) | `text-7xl` | `px-24` | Horizontal row |

- Button row always horizontal (`flex items-center justify-center gap-6`), buttons stack naturally if viewport is very narrow
- Footer: `flex-col md:flex-row` -- copyright and links stack on mobile, sit side-by-side on tablet+
- Subtext constrained to `max-w-xl mx-auto`
- Heading constrained to `max-w-3xl mx-auto`

---

### TYPOGRAPHY DETAILS

| Element | Classes |
|---|---|
| Heading | `text-5xl md:text-6xl lg:text-7xl font-heading italic text-white tracking-tight leading-[0.85] max-w-3xl mx-auto mb-4` |
| Subtext | `text-white/60 font-body font-light text-sm md:text-base max-w-xl mx-auto mb-8` |
| Glass button text | `text-sm font-medium text-white font-body` |
| Solid button text | `text-sm font-medium` (inherits `text-black` from `bg-white text-black`) |
| Copyright | `text-white/40 font-body font-light text-xs` |
| Footer links | `text-white/40 hover:text-white/70 font-body font-light text-xs transition-colors` |

---

### BUTTON DETAILS

**Primary CTA ("Book a Call"):**
`liquid-glass-strong rounded-full px-6 py-3 text-sm font-medium text-white flex items-center gap-2 hover:bg-white/10 transition-all font-body`
- Glass background with gradient border via `::before`
- `ArrowUpRight` icon at `h-5 w-5`

**Secondary CTA ("View Pricing"):**
`bg-white text-black rounded-full px-6 py-3 text-sm font-medium flex items-center gap-2 hover:bg-white/90 transition-colors font-body`
- Solid white background, black text
- `ArrowUpRight` icon at `h-4 w-4` (slightly smaller than the primary)

---

### EXACT TEXT CONTENT

**Heading**: "Your next website starts here."
**Subtext**: "Book a free strategy call. See what AI-powered design can do. No commitment, no pressure. Just possibilities."
**Button 1**: "Book a Call"
**Button 2**: "View Pricing"
**Copyright**: "(c) 2026 Studio. All rights reserved."
**Footer links**: "Privacy", "Terms", "Contact"

---

### PARENT CONTEXT

This section sits on a `bg-black` parent container as the last section of the page. The top gradient fade blends the video into the section above (which also has a black background). The footer bar is part of this same component -- there is no separate footer component.
