/*
 * Layout is Posterous's stock "cleansheet" theme, recovered from a 2012
 * Wayback capture: the date sits in a left gutter, the text column is narrow,
 * the leading is generous.
 *
 * Colour is Flexoki by Steph Ango (MIT, stephango.com/flexoki) — a warm paper
 * and a warm near-black rather than white and black, which is what keeps a
 * page of family photos from feeling like a dashboard.
 *
 * Type is deliberately flat: headings sit at weight 500 and only a little
 * larger than body text, so hierarchy comes from colour and space instead of
 * from shouting.
