We already have a pattern for navigation folders and searching for
templates – let’s use it for the copy page too. And I reckon we can
represent services as folders if the user has multiple services they
could copy a template from.
After showing this to a few people the consensus seems to be that
‘Templates’ isn’t itself a folder. Therefore it shouldn’t have a folder
icon.
This has the advantage of disambiguating between being in a folder:
> [screenshot]
…and being in a subfolder:
> [screenshot]
This makes the display of folders in the `<h1>` look like the prototype.
It alters the behaviour we’ve initially built here by only ever showing
a maximum of two levels of hierarchy (the current folders and its
parent).
