/* The legal pages (public/legal/page.html, ADR 0100): a document to read.
   One column below 992px: the title, any notice, "On this page" as a
   bordered box, the text, Earlier versions. From 992px the contents list
   moves into a 15rem column beside the text and stays in view while the
   text scrolls (sticky, below the navbar's clearance from
   scroll_clearance.js), scrolling on its own when it's taller than the
   window; it holds only links, so the keyboard reaches all of it. The text
   column is capped near 75 characters a line. Greys meet 4.5:1 on white
   (#5c6672 is 5.8:1, #424245 10:1). */
