What a form needs to render, independent of where it came from.

Fields

module: &'a str

action: &'a str

post_to: &'a str

POST target; the /ui route, never /v1.

intro: Option<&'a str>

A paragraph above the fields (from the UiSpec).

fields: &'a [Field]

values: &'a Values

errors: &'a [(String, String)]

Field name to message; a key of "" is the form-level error.

captcha_site_key: Option<&'a str>

Turnstile site key when the action wants a captcha and one is configured.

submit_label: &'a str
