pub const FIELD_CLASSES: &[&str];Expand description
Every class this module can put in markup.
crate::facet::FACET_CLASSES’ obligation, and the module where it was
missing longest. Every one of these is ruled by the generated sheet, the
group’s four through [group_rules]; the list is written down anyway,
because it is what [crate::corpus] holds the emitters against and what the
vocabulary test holds the sheet against.
What goes wrong without it: an app checking its stylesheet against
crate::vocabulary::names concludes that its live .form-group and
.form-label rules match nothing and are safe to delete.
