- pi_hifiberry_amp: the boot config lives at /boot/firmware/config.txt. - pi_sysdweb: install python3-dbus and python3-systemd from apt, which trixie ships at the versions sysdweb needs; bookworm gets the headers pip needs to build dbus-python 1.4 itself. - pi_squeezeserver: trixie images have no iptables, and so cannot have the port 80 redirect that absent.yml removes - skip that step there instead of failing. - pi_modern_shell_env, pi_slint_frontend: read facts through `ansible_facts` rather than the deprecated injected `ansible_*` variables.

# ~47 MB of swap is worth reclaiming.
