/* ------------------------------------------------------------------ 1. Tokens
 *
 * Warm, quiet neutrals with a single olive accent reserved for actions and for
 * anything that means "recorded". Two accents at most — everything else is
 * neutral, so a filled cell in the log reads as information rather than as
 * decoration competing with six other colours.
 *
 * Deliberately warm rather than clinical, and deliberately not the red/amber/
 * green vocabulary the rest of this category uses: nothing on this site scores
 * a meal, so nothing should be coloured as though it had.
