Per the design, ely://settings opens directly on the appearance form
(serif "Appearance" headline + wallpaper grid + theme/accent/motion
rows), not a route summary. The settings layout's right column now
delegates to render_appearance_form so /settings and /settings/appearance
share the same canonical form rendering.
The metric cards / "Jump in" list helpers and the METRIC_BG constant
are deleted — they were only referenced by the previous summary right
column. Left nav still highlights Appearance as active when the user
lands on /settings.
