/* Laptop design system.
   The whole site is one desk: a warm paper ground, ink text, and cards that read
   as small windows (hairline bezel, a quiet chrome bar with three square lamps).
   One accent, Base blue, carries every action. Numbers are always lining and
   tabular so columns line up. No emoji anywhere: icons are inline SVG in ui.js. */
