/* ==========================================================================
   Journal reminders (js/components/nudges.js): one small bubble above the
   assistant's pill, once a day - a quiet title, up to three lines, a close
   button.
   The operator 31.10: "a bubble, not a table - delicate, like the field we
   type a message in", then "make it glass". So it has the composer field's
   shape (.help__input: 22px round, a hairline ring, a small tail toward the
   pill) in glass, as the pill and the composer's dock are made: a thin tint
   over a blur of the page. The lines are plain text, no box and no rule
   between them. No shadow, no glow, no pulse, no gradient, no new colour.
