/* THE CITY IN LETTERS LARGE
 *
 * The world is drawn on canvas and is not styled here. This file styles the
 * overlay only, and its job is to stay out of the city's way: dark, translucent
 * chrome at the edges, warm parchment ink, and nothing that looks like
 * educational software.
 *
 * Deliberate absences: no progress-bar green/red morality colouring on the
 * metrics (valence is carried by a subtle left border, not by traffic lights),
 * no XP, no badges, no score.
