Font-width CSS property and @font-face descriptor docs are missing

[pepelsbey]

BCD

• Support for the font-face property added in Safari 18.4 (31.03.2025)
• Support for the font-face descriptor added in Safari 26 (15.09.2025)

It’s a little tricky because it’s a new name for an old property/descriptor.

MDN

• font-stretch property
  Marked as deprecated, font-width is mentioned as “not yet supported by any browsers”.
• font-stretch descriptor
