$ Settings
Display and accessibility preferences for this site — applied immediately and everywhere, not just here.
## THEME
Light or dark. Defaults to your OS preference until you choose one explicitly.
## FONT_SIZE
Scales all text on the site proportionally — nothing to configure per page.
## REDUCED_MOTION
System follows your OS’s reduced-motion setting; On or Off overrides it either way. Actually disables the nav rail’s slide animation and the on-page outline’s smooth scroll-to-section, not just a stored flag.
