   ONE stylesheet for every page. Tune the whole site from the :root variables.

   Light bands are warm cream / smokey grey (not bright white) with a subtle
   diagonal-hairline texture so they read like paper, not a glowing screen.
   Dark bands are soft charcoal with a matching faint texture. Bands are flat
   (no angled seams). Edit --paper / --mist / --ink to re-tone everything; edit
   the .band background-image rules to change the texture.
