// Theme definition for a compact glossary layout optimized for space efficiency
//
// This theme provides a dense but readable format with:
// 1. Terms and definitions on same line
// 2. Smaller font size
// 3. Minimal vertical spacing
// 4. Left-aligned groups for quick scanning
// 5. Condensed page references
//
