/* Matthew Annable — booking system stylesheet.
 *
 * Restyled to the guitar-lessons design system: cream paper, Newsreader for
 * headings, Manrope for UI, amber for the one action that matters on a screen,
 * green for accents and selected state. Every selector, class name and id the
 * templates and booking.js rely on is unchanged — this file only changes how
 * things look, never what they are.
 *
 * The two typefaces are declared in fonts.css, which base.html links ahead
 * of this file.
