The shipped config is the product default again - and now guarded
The 1.11.0 archive carried a maintainer's working config: frame_multiplier 3 (an RTX 40 card caps at 2x), the two SR-merge leftovers in the sliders (local_tone 0.75 and skin_structure 0.8 instead of Natural's own 0.50 and -1.0), and two dead dlss_sr keys from the removed feature. A fresh install started outside the profile it displayed, and on a 40-series card the wrong multiplier walked straight into the refusal below.
The defaults are the product defaults now: multiplier 2, Frame Generation off, CPU motion, Natural's four sliders, dead keys gone. A new static check ("config: the shipped defaults") compares the committed config against the profile-derived defaults on every run - the zip-vs-HEAD comparison can never catch this class, because both sides carry the same wrong values. It flagged the old values the moment it was written.
The multiplier is selectable while Frame Generation is off
Locking x2/x3/x4 behind the FG switch is what let the config bug bite: the switch-on ran with the shipped x3, the 40-series runtime refused it, the switch flipped itself back off - and picking x2, the way out, was locked behind that very switch. The group is a preference for the next attempt now: always selectable, the chosen step stays lit while FG is off. The switch still reports the truth; only the way out is no longer behind it.
Tests
128 checks green on the release commit - the new config gate rides the static stage (it fails on the old HEAD by design, and that failure was recorded before the fix).
