🎨 Adopt dark-only theme aligned with axone.xyz

[Copilot]

This PR implements a comprehensive dark-only theme for the Axone Protocol documentation site, ensuring visual consistency with the main axone.xyz website.

Key Changes

Theme Configuration

• Enforced dark-only mode by updating colorMode.defaultMode to 'dark' in docusaurus.config.js
• Removed theme toggle - users can no longer switch to light mode
• Updated footer style from 'light' to 'dark' for consistency
• Updated Prism.js to use vsDark theme for both light and dark modes

Typography Implementation

• Added Google Fonts integration for Inter (body text) and Montserrat (headings)
• Configured font fallbacks to existing Helvetica fonts for reliability
• Aligned typography with axone.xyz design specifications

Color Palette

Implemented the complete axone.xyz color palette as CSS custom properties:

• Background: #191716
• Primary text: #d9d9d9
• Muted text: #959595
• Primary accent: #ff773d
• Brand blue: #044da2
• Success: #13ce66
• Accent alt/focus: #00ff95
• Danger background: #661d1d

Comprehensive Styling Updates

• Rewrote src/scss/custom.scss with dark-only CSS variables
• Enhanced contrast ratios for accessibility compliance
• Styled all UI components including navigation, sidebar, footer, code blocks, and interactive elements
• Ensured consistency across charts, mathematical formulas, and Mermaid diagrams
• Maintained brand assets (logos, favicons) unchanged as specified

Visual Results

The documentation now presents a cohesive dark theme experience:

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

Not what you expected? Are your scores flaky? GitHub runners could be the cause.
Try running on Foo instead
