Welcome to renta.net.
Every page is produced by an operator-authored .mix script running in-process inside cosmix-webd, reading and writing this vhost's own SQLite database through the db_query/db_exec builtins.
The visual shell is the dcs.spa dual-carousel design system — the same one that powers the static template at mmc.kanary.org — with the CMS content rendered into its main column. No React, no build step: just Mix, server-rendered HTML, and the dcs.spa CSS/JS. Edit a handler and reload; the change is live.
