Why won't fonts change in PowerPoint?

PowerPoint ignores explicit font settings when the slide language is set to CJK (zh-CN, ja, ko) or when fonts reference theme placeholders like +mj-lt, +mn-lt. PowerPain fixes both issues by normalizing language attributes and replacing theme references with explicit font declarations.
