/* Oak — marketing site.
 *
 * Plain CSS, no build step, no framework, so Albert can change a sentence or a colour without
 * running anything. The palette and the type pairing are lifted from src/styles.css on purpose:
 * the site and the product should feel like one thing to somebody who sees the page and then the
 * login screen ten seconds later.
 *
 * Fonts are self-hosted and preloaded rather than pulled from Google, because the audience is on
 * Tanzanian mobile data and a blocking round-trip to fonts.gstatic.com is the slowest thing on
 * an otherwise very small page.
