Pier becomes Pierrr, with a new logo

The product is now spelled Pierrr everywhere: public site, console, transactional emails and documentation.
A new logo, in the console, on the public site and in the browser tab. It takes the text color, so it reads on the light and the dark theme alike.
The design system page is public: it is back in the site footer and shows the logo, the logomark and the brand variants for each product (Agent, Security, Mail Relay, MCP, Monitoring, Backup, Topology).

Console pages are much lighter: the world map in the background is downloaded once, instead of being sent again with every page.

The self-hosted agent moves to version 0.48.0-beta and is now called pierrr-agent: binary, systemd unit, configuration and state directories, and environment variables, which move from PIER_ to PIERRR_.
An existing install does not migrate on its own and will not update into this version. Uninstall the agent and install it again, or move the state directory to /var/lib/pierrr-agent/ yourself before reinstalling, to keep the applications and backups it holds.
