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.
