/* pm-module-bands.css — the visible module grouping on a short course page.
 * ---------------------------------------------------------------------------
 * Deliberately quiet. The point is orientation, not decoration: a learner
 * scrolling through 44 lessons should always be able to see which module they
 * are in, how far through it they are, and that an end is coming. Anything
 * louder competes with the lesson cards themselves.
 *
 * The tint alternates between modules rather than being one colour, because a
 * single tint on every band gives you no edge to see when one ends and the next
 * begins — which was the whole problem.
 *
 * Colours are taken from each course's own variables where they exist, with
 * neutral fallbacks so this file drops onto any of the courses unchanged.
