/**
 * The site-wide password gate.
 *
 * Nothing links here. `proxy.ts` rewrites every request to this route while
 * the site is locked, which is what keeps the requested page from rendering
 * at all — a gate in the layout would still let the page produce its RSC
 * payload, album names and asset tokens included.
 *
 * The legal notice and the privacy policy are the exception: the proxy serves
 * them to a locked site, and this page links them, so a visitor who cannot get
 * in can still see who runs the site.
 *
 * /contact is served to a locked site as well, but not linked from here: it is
 * open because the Impressum names it as a contact channel, and the Impressum
 * links it. A form under the password field would read as "ask for access".
