/* NakedERP page: "Laufzettel" (job sheet).
 *
 * Loaded after product.css. The page is a drafting table: petrol paper with a fine plan grid, and on it one sheet that
 * follows a commercial-kitchen project from quote to e-invoice. The one object on the page is that sheet in the hero.
 * It fills itself station by station and then waits for an answer (how much of the final invoice the customer retains
 * as security). The four chapters below each have one CSS loop.
 *
 * Palette: ink #14181a, petrol #00485a (the site's), coral #df9784 (the site's), teal-grey #83a3ac. Coral text on paper
 * is darkened to #9c4a37 (4.5:1). Type: the site's Helvetica, no webfont; monospace is the system's.
 *
 * Motion is CSS only, except the sheet (js/nakederp.js, which sets classes and `hidden`). Base styles are the finished
 * picture; the animations start from the unfinished one, so prefers-reduced-motion just switches them off. */
