/* Serpdigest design system.
   Language lifted from the Mortera reference: warm off-white field, one lime
   accent, dot grid, hairline borders, no shadows on the light page. Machine
   labels (numbers, ranges, property ids) get the mono face; prose gets sans.
   Fonts are the system stack on purpose: no webfont, no FOIT, no third-party
   request. Inter and JetBrains Mono are used when the OS already has them. */
