    fontSize = 16,                    -- Base font size
    nameFontSize = 18,               -- Character name font size
    boxColor = {0.1, 0.1, 0.1, 0.9}, -- Dialog box background color
    textColor = {1, 1, 1, 1},        -- Text color
    nameColor = {1, 0.8, 0.2, 1},    -- Character name color
    padding = 20,                     -- Box padding
    boxHeight = 150,                  -- Dialog box height
    portraitSize = 100,              -- Size of character portraits
    typingSpeed = 0.05,              -- Text typing speed
    fadeInDuration = 0.5,            -- Fade in animation duration
    fadeOutDuration = 0.5,           -- Fade out animation duration
