   mark-tool.css — the workbench chrome.

   mark.css dresses the pages that argue (manifesto, how-it-works). These are
   the pages that are operated: a stripboard, a rate table, a teardown bench.
   Same two colours, same two typefaces, denser everything — a producer scans
   these at 11pm looking for one number.

   Rules that carry through all three tools:
     · paper ground, ink type, no accent hue; --signal (the tally red) is for
       things that are actually wrong, never for decoration
     · numbers are tabular and right-aligned, always
     · a control that changes stored data looks different from one that reads
     · anything unverified says so on the row, not in a legend
