/* NSofts Stay theme.
   Layout: a floating deep-teal sidebar (the one bold element, with faint hill contours) beside a calm mist canvas of
   white panels. Titles in a warm serif, the interface in a clean sans. Phones get a bottom tab bar.
   Every colour is a token; dark mode redefines the tokens only. */
