Host-specific divergence for blankpad deployed last with override semantics:
display layout (its own outputs, not Dankware's DP/eDP rig), autostart and
keybinds targeting the bare 'noctalia' CLI instead of qs -c noctalia-shell,
misc without renderD129, rules without the Noctalia floating-window rule, and
blank's own .zshrc. All other packages deploy canonical from base.
