custom classes for typespec keywords

[hauntedhost]

Currently using "monokai-shade" theme and the styles on typespec keywords are nearly white which is quite "loud", visually distracts from the function definition itself, and unfortunately discourages me from writing typespecs. 😞

I'd love to be able to target and adjust the styles on typespec keywords, e.g.:

• @type type_name :: type
• @typep type_name :: type
• @opaque type_name :: type
• @spec function_name(type1, type2) :: return_type
• @callback function_name(type1, type2) :: return_type
• @macrocallback macro_name(type1, type2) :: Macro.t

I'm thinking similarly to the syntax--documentation class added to @doc moduledocs, tacking on an extra class like syntax--typespec or something.

Any thoughts?
