Line end plan

[dberlow]

See “Emsquare spec In Typetools” below for defaults

Font Spec
Body - 14, 100width, 400wght
Main head 48, 85wdth, 650wght
Pull quote 32, 50wdth, 200wgth
Subhead 28, 100wdth, 750wght
Captionhead 18, 100wdth, 850wght

Line end rules
Body - Cold: size, wght, wdth,
Hot: xtra, track, wordspace

Main - cold: size, wght, track
Hot: wdth/XTRA, wordspace

Pull - cold size, wght, wdth, track
Warm: xtra, wordspace

Sub - cold: size, wght, wdth
Hot: xtra, track, wordspace

Cold means it’s inherited from somewhere else and can’t change from one headline, e.g. to the next.
Hot means it can be used to vary type to fit.
Warm means Only a little of it can be used.

Algorithm?
If default size, wght, wdth, track, wordspace, and xtra

and text is shorter than column

done
(Body, Main, Sub expected to 1 or 2 lines only_

else,
if text is longer than column
and <1 word space beyond column width
then use size-specific equation, Body, Main, Sub
else break line

done.
(Pull, expected to always be >2 lines).

Note: use pull spec for"header"
