Brandon ThomasandClaude Opus 5.5 3e62501373 Text: single-spaced lines are 1.2 times the font size apart, as in PowerPoint ...

PowerPoint spaces single-spaced lines 1.2 x the font size apart in every
font (measured on twenty Latin, CJK, Thai and Indic fonts at 18 and 40 pt
with PowerPoint's slide export) and puts the baseline where the font's
Windows ascent/descent split it. DeckCraft used each font's own ascent plus
descent, so Calibri lines were 15% too tight and Segoe UI ones too loose.

FontFace gains line_split (usWinAscent / (usWinAscent + usWinDescent));
line_metrics uses it with LINE_PITCH = 1.2.
