/* Zilk — shared styles for zilk.io
 *
 * One stylesheet across every page so the marketing pages and the transactional
 * ones (reset-password, confirmed, claim) read as one product rather than as
 * things built at different times. Those three predate this file and keep their
 * own inline styles; the palette here matches them exactly so they still belong.
 *
 * No webfont. A font request is a second point of failure for a page whose whole
 * job is to be reachable, and the system stack on a phone is already the face the
 * app uses.
