/* Colour tokens: every colour in every stylesheet comes from these blocks and nowhere else.
   Light "QuickBooks" (the default): charcoal navigation and a green accent, darkened just enough that white
   button text and green text pass 4.5:1. Dark "Edgewood": near-black surfaces and the gold of the logo. The dark
   tokens apply with html[data-theme="dark"], or with no data-theme when the device prefers dark (static/theme.js
   sets data-theme from the choice in the account menu). They are screen-only, so printing always uses the light
   tokens: dark text on white. */
