/* zen.css (2026-10-14): the fishtank.cam pass. Loaded last; overrides app.css, pager.css and diagrams.css.
   An iwagumi feel: calm space, stone greys, moss green, off-white and ink; thin rules; a quiet serif for headings.
   Also: the sectioned nav, the pages column (one column inside, drag to resize, swap sides), "more below" and the
   previous / next cards, the camera crop, the calendar, the schedule, the thermometer and the drop checker. */
