/* mymemos.reddec.net — the app's palette, one card at a time.
   Warm paper, ink, soft white cards and one calm indigo accent. Notes set in
   sans, display sizes in serif; nothing uppercase, nothing monospace. Light and
   dark follow the system: the site has no theme switch because the app has none
   either. No JavaScript anywhere. */
