text-wrap: balance isn't just for headlines
Terence Eden notes that text-wrap: balance isn't limited to headings — it works on any content, including rows of icons. If a viewport gets too narrow and a single icon drops to the next line, balance can handle that layout hiccup with a simple one-liner instead of a more complex auto-fitting grid.
The spec does have opinions, though. Per the CSS Text Module Level 4, the balance value is intended for titles and captions, and the content in question should be fewer than five lines. There may be more nuance ahead: a spec issue suggests extending the value space to something like match-indent | <length> | <percentage>, with an option for an <integer> that counts characters.
