/* fabrknt shell v1 */
/* The shared look of fabrknt.com ("Warm Instrument", design C5). Framework-free: tokens are CSS custom
   properties on :root; every class is prefixed fk- so the file can sit next to other stylesheets
   (the record pages, the reading pages, later the Next.js site) without touching their rules.
   Base type applies only inside <body class="fk">, at zero specificity (:where), so page rules win.
   Language: <html lang="ja"> hides .en, any other lang hides .ja (English shows without JavaScript).
   Theme: prefers-color-scheme, overridden by <html data-theme="light|dark">. */
