Interface MailComponentTemplate

The component arm of MailTemplate (M102): bodies rendered through the view engine registered under CAPABILITIES.VIEW, with sendTemplate's data passed to each component verbatim as its props.

Configuring one requires a CAPABILITIES.VIEW provider — MailPlugin refuses at register() otherwise, naming both remedies. Escaping is the rendering runtime's (a JSX component and an html tagged template escape their interpolations; a hand-written template literal does not — the caveat IViewEngine.render states applies unchanged to a mail body). Unlike the string arm, there is NO missing-key check: a component reads whatever it reads, so a key absent from data renders as undefined rather than throwing. The compile-time route is to call engine.render(Component, props) and mailer.send by hand.

Component<never> is the one type every component is assignable to; the props are not checked at this boundary because the committed IMailer.sendTemplate types data as Record<string, unknown>.
