 * FareGoal — navy #1F3557, gold #D4AF37, white.
 *
 * Navy does the work and gold is the jewel. That split is forced by contrast,
 * not taste: brand gold on white is 2.10:1, so it can never carry text in the
 * light theme. It appears there only as the logo, borders and fills. On the
 * navy surfaces of the dark theme it reaches 5.86:1 and becomes the accent.
 * Every pair below was measured, not eyeballed.
