/* Kamin AI site styles.
   Three colours only: Falu red, black and white, in two themes: dark (white on black, the default)
   and light (black on white), chosen by data-theme on <body>. Use the --fg/--bg tokens rather than
   --white/--black so both themes work; --white is only for text on a red fill.
   Greys are the foreground colour at reduced opacity.
   Red on black is low-contrast, so red is only used for fills, rules and highlights, never for text. */
