Overview

Configuration class for layer-specific styling and positioning that centralizes all hardcoded values used across different layers. This class provides a centralized configuration system for font sizes, positioning, frame styling, and other layer-specific settings.

Examples:

config = MtgCardMaker::LayerConfig.new
config.font_size(:name) # => 32
config.corner_radius(:outer) # => { x: 25, y: 25 }

Custom configuration

custom_config = {
  font_sizes: { name: 36, type: 24 },
  padding: { horizontal: 20 }
}
config = MtgCardMaker::LayerConfig.new(custom_config)
