/* 28 of the 34 figures in this book are line art saved with an alpha channel:
   black strokes on a transparent background. Against the dark theme they are
   very nearly invisible.

   Give figure images a light plate in dark mode. This is deliberately not a
   `filter: invert()` - inverting works for pure line art but ruins the
   photographs and colour micrographs (SIM sections, Jablonski diagram, the
   light-sheet panels), and this book has both. A plate is safe for every kind
   of image. */
