/* =====================================================================
   styles.css — one stylesheet for every page.

   Clean, minimal, BLACK design. The page is always black (there is no
   light theme, on purpose: color-scheme is locked to dark).

   RE-SKINNING: every colour, font, radius and shadow lives in the token
   block at the top. Change the green in ONE place (--accent) and the hover,
   pressed and tinted shades follow (they are derived with color-mix).
