Brandon ThomasandClaude Opus 5.5 55a53f8ecb Fonts: missing fonts draw as PowerPoint draws them, and Windows family names resolve (#322)
* Text: a missing font is drawn in Calibri, as PowerPoint does

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

* Fonts: Windows family names find their faces; PowerPoint's twins for missing fonts

"Segoe UI Semibold", "Arial Black" and the like are the faces' Windows (GDI) family
names; a family's installed files now load together; Liberation Sans and Serif draw as
Arial and Times New Roman when missing, as PowerPoint draws them.

* Fonts: Office cloud fonts (Aptos…) keep their open substitute
