Enable Goldmark block-level attributes so the relearn `children`
shortcode applies its CSS classes instead of printing them literally
in the table-of-contents pages. Also expand the deploy, plugins,
records, and email reference docs and add the checks pages.
The theme overhauled its logo system to render #R-logo > .logo-image,
making the old layouts/partials/logo.html override (#logo > img) match
no CSS, so the wordmark overflowed the sidebar.
Remove the stale override and use the theme-native logo config: point
params.logo.src at the wordmark, suppress the redundant text title, and
declare the auto variant's light/dark variants explicitly so the
variant-gated logo also shows in dark mode. Set --LOGO-IMAGE-width to
90% in custom-header.html to fit the wide wordmark.
