We suggest overriding the template(s) involved in this. You can use a
custom theme or just the templates folder. Most HTML customizations
will involve overriding a template. You do need to remember about
overrides when you change themes, and it might sometimes be necessary
to check for changes in upstream templates, but this is generally a
minor issue.
>From a quick look, it seems you would need to override
base_helper.tmpl. Since `post` is not always defined, you will need an
if to check that, the easiest way would be to do it via `pagekind`.
And then, you could just do another check for post.meta('canonical')
and insert that instead of the permalink if it’s not blank.
