/* app.css — CARD.
 *
 * The house look: light and corporate by default, warm rather than clinical
 * because the product is greeting cards. One stylesheet, no framework, no
 * webfont — the page must render immediately and completely on a phone with a
 * bad connection, since the whole site is server-rendered HTML anyway.
 *
 * The cards themselves bring their own colour. Everything around them is
 * deliberately quiet so twenty-five of them in a grid do not fight the
 * furniture.
