/* ===== Daily Check-in: breathing "today + checked-in" cell =====
   When today already meets a goal, the cell carries BOTH .is-today and .is-on and
   breathes between its two looks: the check-in look (green fill + colored dot) and
   the today look (no fill + green border + idle dot). A non-checked today never
   matches .is-on, so it gets no animation and keeps its static look.

   The dark theme paints fill/border/dot with !important, which @keyframes cannot
   override; so the cross-fade is driven by opacity on fresh overlay pseudo-elements
   (immune to !important) instead of animating the locked color properties. The
   cell's own is-today ring stays lit throughout — only fill + dot breathe. */
