/* Two newspaper columns rather than one long scroll.

 * A label column beside the value was self-defeating: widening the popup to
 * 620px and putting the labels back left the prose exactly 407px, the same
 * as before. The width has to go into the text, not into a gutter. Flowing
 * the facts into two columns spends it properly — each column sits near 350px
 * (~55 characters, comfortable) and the popup is half as tall, so it stops
 * scrolling entirely on a normal screen. */

   Open articles, not accordions: on a dedicated page there is nothing to

   the FAQ was the one page with no card background, plain text floating on
   the page background while the calculator and About both read as panels. */
