/* === Date and time picker — assets/js/date-picker.js =========================
   One control for every date on the site. It speaks tokens.css only: every
   colour is a --dp-* variable defaulting to a token (the reminders page remaps
   them to its own palette — reminders.css, .rm-page and .rm-page .dp-panel), and
   every gap, padding and radius is on the --s-* / --r-* scale. Both pages that
   load it load tokens.css first. */
