/* The public /trading-performance page.
 *
 * Loads after trades-page.css and portfolio-page.css and adds only what this
 * page needs. The three product pages share one vocabulary on purpose — the
 * section furniture, the widget frame, the table and the jump nav are all the
 * same elements. What is different here is the SKIN: this page is drawn as a
 * data sheet, because its whole claim is that every figure can be checked.
 * A field name, a dotted leader, the number, and underneath it the sentence
 * that says what the field means. A card with a big number and a gradient
 * behind it would be making the opposite promise.
 *
 * Green and red appear only on a figure that is genuinely a gain or a loss.
 * A profit factor, a payoff ratio and a win rate are not results — they are
 * ratios, and colouring them would tell the reader something the number does
 * not say.
 *
 * Nothing here is drawn by JavaScript. The curves are paths the server has
 * already computed, so they are in the document with scripts blocked and in
 * a search index.
