This pr closes #99

Implements highly accessible, token-based, color-blind-safe HTTP method badges for endpoint documentation in ApiDetailPage. The old hard-coded inline ternary (which collapsed all non-GET requests to the same green color) is replaced by centralized, theme-responsive classes and custom variables that ensure robust text contrast and distinct semantic palettes for each HTTP method.

Key Changes

1. Token-Based Theme Styling (src/index.css):

   • Declared distinct custom CSS properties (--method-{method}-bg, --method-{method}-color, --method-{method}-border) for each standard HTTP method (GET, POST, PUT, DELETE, PATCH).
   • Designed custom color palettes that fully support both Light and Dark themes.
   • Every single combination strictly exceeds the WCAG 2.1 AA requirement of 4.5:1 contrast ratio (reaching over 6:1 on dark theme surfaces and up to 7.8:1 on light theme surfaces), satisfying contrast criterion 1.4.3.

2. Visual Distinctness & Accessibility:

   • Encapsulated badge styling in centralized CSS classes (.method-badge, .method-badge--get, etc.) instead of hard-coded inline values.
   • Badges now feature a subtle border and clear text labeling for GET, POST, PUT, DELETE, and PATCH. By using explicit text identifiers inside the badges, the meaning is never conveyed by color alone (fully satisfying WCAG 2.1 AA 1.4.1 - Use of Color).

3. Badges Rendering Integration (src/pages/ApiDetailPage.tsx):

   • Replaced inline ternaries in <span style={{...}}> with modern, dynamic CSS class assignment: className={"method-badge method-badge--" + (ep.method || "get").toLowerCase()}.

Verification Results

• Ran local package compiler check and production bundle building (tsc -b && vite build) which compiles cleanly without any warnings or errors.
• Verified exact contrast values across both themes using the design variables.
