/* Dirty Water Tracker — shared styles.

 * Loaded first by every page; each page's own sheet (css/<page>.css) follows
 * and may override. The look is deliberately quiet: neutral chrome, hairline
 * borders, one accent for links and focus, and colour reserved for the data
 * (venue types, sync status, map pins), so a coloured element always means
 * something. Tokens first, then components.
