Left to do by hand:
  1. Reboot, pick Hyprland in ly and log in.
  2. Press SUPER+W once to choose a wallpaper.
  3. Open nvim once and wait for Mason to install the language servers.
  4. Restore ~/.ssh and ~/Documents/Writing from your private backups.
  5. Sign in to Proton Mail, Brave, Spotify and Claude.
