PPT Font Fix

Problem

PowerPoint's "Export to PDF" can fail to embed downloaded/custom fonts, substituting built-in defaults, even when:

• Fonts are properly installed and embeddable
• "Embed fonts in the file" is checked in PowerPoint options

Workaround

Applying a tiny transparency (1%) to text with 0% transparency forces PowerPoint to correctly embed fonts in PDF output. This is visually imperceptible but changes how PowerPoint processes the font during export.

Usage

python3 scripts/fix_font_transparency.py input.pptx [output.pptx] [--transparency 1]
