Overview

Mana cost class that generates SVG for the mana cost of a card. This class parses mana cost strings (e.g., "2UR", "XG") and generates SVG circles with appropriate colors and icons for each mana symbol.

Examples:

mana_cost = MtgCardMaker::ManaCost.new("2UR")
svg = mana_cost.to_svg

mana_cost = MtgCardMaker::ManaCost.new("XG", icon_set: :custom)
svg = mana_cost.to_svg
