/* One root size, everywhere. Everything else is a rem multiple of it, so this
   is the single scale knob for the site: type, spacing and the page width all
   move together and the proportions never change. 89.5% of a 16px default is
   14.32px, putting body text at 15.2px - set by eye. A percentage, not a pixel
   value, so a reader who has set a larger default font size still gets 89.5%
   of theirs rather than ours.

   The root size used to scale UP past 100rem and 140rem of viewport width, on
   the theory that a wide viewport means a big monitor. It doesn't: Linux
   browsers usually report devicePixelRatio 1 whatever the panel density, so a
   15" laptop claims the same CSS width as a 27" desktop and got the same
   upscaling. That rule was why the site came out a different size on every
   machine, and why each browser needed its own zoom level to look right.
   Physical display size is not knowable from CSS - zoom and the reader's own
   default font size are the knobs for it, and both work normally now. */

   Two variants, so they can be compared head to head:

     <html data-grain-cards>  texture on the work card images only
   Flip either live, no rebuild:

   'overlay' was the obvious choice and is the wrong one: on a near-white
   ground it compresses to almost nothing. The tile is mostly white with
   sparse darker specks, multiplied on light and inverted/screened on dark.
