/* Kitagishi homepage — shared styles
   Palette: black/white base (from the old STUDIO site) plus two accents
   pulled from assets/kitagishi-cv.pdf — --accent is the CV's one accent
   color (the small square markers/rules), --accent-brown is sampled from
   the wood-grain background in the profile photo. Used sparingly: links
   and the active nav state get --accent, muted/secondary bits (dates,
   list numbers) get --accent-brown. */

   back to the system fonts later in --font-body.
   font-display: optional (paired with <link rel=preload> in each page's
   <head>) avoids a visible fallback-to-Open-Sans swap: the browser only
   uses Open Sans if it's ready essentially immediately, otherwise it just
   keeps the fallback for that page view instead of swapping mid-render. */
