Overview

Centralized configuration for log level icons and colors

Single source of truth for all logging/notification output across the codebase. This ensures consistent styling and makes it easy to customize icons and colors for all log levels in one place.

Examples:

Using LogStyle with Pastel

pastel = Pastel.new
puts LogStyle.format(:success, "Operation completed", pastel)
# => "\e[32m✔ Operation completed\e[0m"

Getting icon and color separately

icon = LogStyle.icon(:error)    # => "✗"
color = LogStyle.color(:error)  # => :red
