Can you give the Appearance panel a hue/sat/contrast fader, plus a way to save custom themes?
Done — drag the sliders in the panel on the right for a live preview, then name a look and hit Save theme to keep it. Everything persists through the normal settings path, with a local fallback for a fresh visit.
What's the new default skin called?
Ame — twilight indigo/violet, full light + dark token set, not just an accent-color swap.
