[Feature Request] Please Add "Material Gruvbox" (Dark Theme) - CSS Included

[deltaxsingh]

Feature Description
I would like to request the addition of a Material Gruvbox color scheme option to the list of available Dark Themes within the Anupuchin "Style Settings" configuration.

I have personally customized the Anupuchin theme to use the Material Gruvbox palette. Since Anupuchin already supports multiple preset color schemes, adding this would provide users with a popular, retro-inspired high-contrast option without needing manual snippet management.

Implementation Note:
I am not a developer, so my implementation currently works by applying the CSS snippet below on top of the "Rose Pine" (or Rosebox) preset in Style Settings. I used that as a base to ensure any un-styled variables (like borders or specific interactive elements) maintained a cohesive look.

• Note to Dev: My snippet directly overrides the standard Obsidian variables (e.g., --background-primary, --text-normal). I noticed your extended-colorschemes.css typically uses internal mappings (like --ctp-ext-rosewater). You may need to adapt the RGB/Hex values below to fit your specific ctp-ext mapping system.

Miscellaneous Features
I have also created a specific fix for the Title Bar to ensure it blends seamlessly with the Gruvbox background colors.

Title Bar Fix CSS:

/* Force window control background to match main title bar */
body {
  /* Common variable for title bar backgrounds in AnuPpuccin layouts */
  --titlebar-background-focused: var(--tab-container-background, var(--background-secondary));
  --titlebar-background: var(--tab-container-background, var(--background-secondary));
}

/* Target the specific container for the buttons */
.titlebar-button-container {
    background-color: var(--titlebar-background-focused); 
}

/* Ensure buttons themselves are transparent */
.titlebar-button {
    background-color: transparent !important;
}
.titlebar-button:hover {
     background-color: rgba(var(--ctp-text), 0.075) !important; 
}
