/* The free deal simulator (/learn/deal-simulator, assets/learn-deal.js), in
   the Learn page's look (shop.css: sh_ panels, fields and banners). Prefix ld_.

   Four colours, each the mark of one party or one way to put the music out:
   amber for you under the deal, magenta for the label, blue for a
   distribution deal, green for going on your own. Chosen as a set for this
   dark surface and run through the dataviz palette validator on 2026-10-27:
   the two in the first chart and the three in the second stay apart under
   protanopia and deuteranopia (worst pair 8.4 and above, against a floor of
   8), and each clears 3:1 against the panel. Text never wears them: a key, a
   stripe or a line beside the words carries the colour. */
