/* QA pass 2: Classes, Continuum field, Forces, Spectrum (classes.js, readout.js, space.js, space_forces.js, spectrum.js).
   One page column of at most 1600 px with 24 px sides (16 px below 700 px). One grid with 16 px gaps: thirds, 2 : 1 or
   1 : 1 above 1100 px, two columns below 1100 px, one column below 700 px. Card padding 20 px (16 px below 700 px).
   Type scale: page title 26/700, section title 18/700, card title 15/700, kicker 11 uppercase .14em, body 14, small 12.5.
   Status chips: one pill, 11 px, weight 700, uppercase, .06em, 1 px border and text in the status colour, no fill.
   This sheet is linked before design-a.css and design-b.css, so rules that meet theirs repeat the page id to win. */
