Text styles (expression markings, tempo markings &c.)

[Reuben Thomas]

Another basic question, but again, I can't find the answer in the docs:
does LilyPond (2.1.25 in my case) have standard text styles for expression
markings, tempo markings &c.? All I've found in the docs and from pieces
on mutopia.org is ad-hoc font settings (using \bold, \italic, \large &c.)
which seems rather unsatisfactory.
