   ShareFam — rhythm.css
   The "Today Together" surface: the total, the household clock line, the
   degraded banner and the five source cards.

   DEV_GUIDE constraints this file is written to, and how each is met:

   #1  ZERO px. Every length here is rem, %, ch or a viewport unit. A single
       px would pin a family's chosen text size and make the 360-pixel-wide
       layout (#5) unreadable for anybody who scales their browser up.
   #2  Light AND dark. The tokens come from `sharefam.css`; this file adds
       only what a rhythm card needs, and adds it for BOTH themes — via
       `prefers-color-scheme` and the `[data-theme]` attribute the theme
       controller stamps, so the toggle wins over the OS in both directions.
   #4  A long day scrolls INSIDE its card rather than pushing the page; the
       dialog height cap (85vh AND 85dvh) lives in `sharefam.css`.
   #5  Mobile-first from a 360-pixel-wide viewport: one column by default, a
       grid only once there is room.
   #6  Motion 150-300ms, and NONE for a reader who asked for none.

   THE TONE OF A CARD IS NEVER THE ONLY SIGNAL. A source ShareFam could not
   read shows an em dash instead of a number, the server's own sentence, and
   a written warning — the colour is the third signal, not the first. Colour
   alone is unreadable for the ~1 in 12 readers with a colour vision
   deficiency and invisible to a screen reader for everyone.
