/*
Key Format Structure Explanation:

The key format uses a combination of:
1. Unicode box drawing characters (│ ┌ ┐ └ ┘ ┬ ┴) for borders
2. ANSI escape codes for cursor positioning (\u001b[...)
3. Format variables ({icon}, {sysname}, etc.)
4. Constant references ({$1}, {$2}, etc.)
5. Color formatting ({#color})

ANSI Escape Codes Used:
- \u001b[s      - Save cursor position (ESC[s)
- \u001b[u      - Restore cursor position (ESC[u)
- \u001b[nC     - Move cursor right n columns (ESC[nC)
- \u001b[nD     - Move cursor left n columns (ESC[nD)

This creates a table-like layout with fixed column widths and proper alignment,
regardless of the actual content length in each field.

For more ANSI escape code reference, see:
