/* =====================================================================
   Yuki website / sign in + link your PC. The same catalogue voice as the
   landing, in a quieter room: one clearing, one field, one thing to do.
   Round 2 (18 Oct): readable sizes (nothing a person reads under 13 px; mono caps tags 12.5 px), the shared fx
   vocabulary (css/fx.css + js/fx.js: crop on the cards, matrix on the main key, lit rows, pulse on live dots), a
   sliding dotted tab indicator, a rolling resend countdown, dot carets in the code boxes. Less copy.
   Load after base.css and fx.css.
