/*
 * cherryAD, typeset.
 *
 * One stylesheet for every page the exchange serves. It lives in a file rather
 * than a <style> block because the site sends `style-src 'self'` with no
 * unsafe-inline: an inline block is dropped by the browser and the page arrives
 * naked. Nothing here may be moved back into the HTML.
 *
 * The look is a printed instrument rather than a brochure — a hairline ledger
 * rule running down the page, labels hanging out in the margin the way
 * marginalia sits beside a contract, receipts with a torn top edge, and every
 * figure set in tabular numerals so columns of money line up.
