The script's jq fallback for .theme was hardcoded to "nord", which
drifted from the lib/state-schema.nix default of "summer-night". With
no state.json (or a blank one), nomarchy-theme-bg-next would look up
backgrounds under themes/palettes/nord/ while the rest of the system
treated summer-night as active — a quiet inconsistency that produced
"no backgrounds found" errors on a system that hadn't yet written a
theme to state.
Matched it to the schema default. lib/state-schema.nix remains the
single source of truth.
