### Define Nebula Color Palette in YAML

Source: https://context7.com/misterio77/base16-nebula-scheme/llms.txt

The scheme definition file maps base00 through base0F to specific hexadecimal color codes. This YAML structure is the standard format required by Base16 template builders.

```yaml
scheme: "Nebula"
author: "Gabriel Fontes (https://github.com/Misterio77)"

# Background and foreground shades (dark to light)
base00: "22273b"  # Default Background
base01: "414f60"  # Lighter Background (status bars, line numbers)
base02: "5a8380"  # Selection Background
base03: "6e6f72"  # Comments, Invisibles
base04: "87888b"  # Dark Foreground (status bars)
base05: "a4a6a9"  # Default Foreground
base06: "c7c9cd"  # Light Foreground
base07: "8dbdaa"  # Lightest Foreground

# Accent colors for syntax highlighting
base08: "777abc"  # Variables, XML Tags, Markup Link Text
base09: "94929e"  # Integers, Boolean, Constants
base0A: "4f9062"  # Classes, Markup Bold, Search Background
base0B: "6562a8"  # Strings, Inherited Class, Markup Code
base0C: "226f68"  # Support, Regular Expressions, Escape Characters
base0D: "4d6bb6"  # Functions, Methods, Headings
base0E: "716cae"  # Keywords, Storage, Selector
base0F: "8c70a7"  # Deprecated, Embedded Language Tags
```
