chrome: feature pages headerless (own header) — topnav stays, profile bar + switcher gone
EPK/downloads/link-in-bio/shows/newsletter have their own header → the site
profile bar + view switcher are redundant there. _headerless extended with those
bodyClasses (on-epk/on-download[s]/on-linkbio/on-shows/on-newsletter); topnav
stays.
Robin 2026-06-18 (EPK page): "the top part can go, keep the nav".
