/**
 * Aphasia Studio — Fleet Design Tokens
 *
 * Single source of truth for the action-color language used across ALL
 * exercise widgets (NEXT-UP fleet polish item 5):
 *
 *   BLUE  = "where to READ / LOOK"  (passages, prompts, directive instructions)
 *   GREEN = "CLICK HERE"            (primary actions, advance, submit, steppers)
 *   AMBER = "HELP lives here"       (hint buttons, hint boxes, scaffolds)
 *
 * Values were unified from the existing fleet: math/clock green action
 * surfaces, math directive-blue instruction band, and the fleet amber
 * hint family. Widget-local custom properties (--mp-*, --cp-*, --cal-*)
 * should migrate to reference these as files get touched.
 *
 * Loaded as a dependency of universal-header.css + shared-components.css,
 * so it precedes every widget stylesheet that uses the variables.
