{% comment %} `fill` marks the page as one that wants the shell's height rather than its content's. `mvp-page-fill` is what the shell keys off (see the rule in mvp/tailwind/base.css) — the shell cannot otherwise know, because this component renders inside the content block, long after the shell around it. It also drops `mb-16`: a bottom margin under a page that is already exactly as tall as the space it was given is 4rem of overflow. {% endcomment %}
