/* CS Job Board. One stylesheet, no build step, no external fonts.
 *
 * Direction: a printed classified sheet. A student scans this the way you
 * scan the back pages of a newspaper, so the page is ruled rather than
 * carded, dense rather than airy, and warm paper rather than dark glass.
 * A serif carries the thing you read (the job title) and a monospace carries
 * everything you compare (employer, counts, chips, controls). One accent, a
 * printer's rust red, and it is spent on two things only: the match rail and
 * the current filter.
 *
 * The page is light on purpose and does not follow the system dark setting.
 * Paper is paper. Every text pair below was measured against WCAG AA:
 *
 *   ink on paper            15.70
 *   ink-soft on paper        7.14
 *   ink-soft on band         6.23
 *   accent on paper          6.94
 *   accent on band           6.05
 *   paper on accent          6.94
 *   paper on ink            15.70
 *   have on have-bg          7.34
 *   working on working-bg    6.79
 *   ink on have-bg          14.09
 *   ink on working-bg       14.00
 *   rule-ui on paper         3.42  (borders, meets the 3:1 non-text bar)
