Text Before HTML:

We are building a cross-platform video-editing web app with a professional neutral gray UI, inspired by the provided template but tailored for a video editor.
 The app should include:
   - Timeline with nested tracks
   - Magnetic snapping
   - Clip properties dialog
   - LUT color grading preview
   - Export preset wizard

 We'll use Tailwind CSS for styling and aim for a clean, modern design.

 Steps:
 1. Define a color scheme that is professional and neutral (similar to Premiere Pro's dark theme).
 2. Structure the layout with a header, main content area (with timeline and preview), and a properties panel.
 3. Implement the timeline with nested tracks (using a collapsible structure).
 4. Add magnetic snapping functionality (snap to grid or markers).
 5. Create a clip properties dialog that appears when a clip is selected.
 6. Include a color grading section with LUT preview.
 7. Design an export wizard.

 We'll use the following color palette (inspired by the template but adjusted for a video editor):
   - Background: dark gray (similar to the template's --token-bg-dark: rgb(11, 11, 11))
   - Text: light gray and white
   - Accent: a professional blue (instead of the green in the template) for buttons and highlights.

 Let's define:
   --token-bg-dark: rgb(11, 11, 11);
   --token-bg-dark-secondary: rgb(23, 23, 23);
   --token-text-light: rgb(255, 255, 255);
   --token-text-light-muted: rgba(255, 255, 255, 0.6);
   --token-accent: rgb(66, 153, 225);  // RoyalBlue for a professional look
   --token-accent-light: rgba(66, 153, 225, 0.2);

 We'll structure the page:

  Header: 
    - App name, menu (if any), and user controls.

  Main Content:
    - Left: Timeline (with nested tracks) and a preview area.
    - Right: Properties panel (initially hidden, toggled by a button) that shows clip properties, color grading, etc.

  We'll use a grid layout for the main content.

  Timeline:
    - A vertical timeline with tracks (each track can have multiple clips).
    - Tracks can be nested (collapsible).
    - Each clip in the timeline can be dragged and dropped, and snap to the grid.

  Properties Panel:
    - When a clip is selected, show properties (like start, end, effects, etc.)
    - Color grading section: a preview of the video with the current LUT applied, and a set of preset LUTs.

  Export Wizard:
    - A modal or a section that guides the user through exporting the video.

  We'll use the following Tailwind classes and custom styles.

  Note: This is a static HTML/CSS representation. The JavaScript for interactivity (like the timeline, snapping, etc.) would be implemented separately.

  Let's start coding.
