//| 1.2: the lines drawn as a risk/reward box (Chart Kit): loss and |
//| profit zones behind the candles, a tag on each line with its     |
//| price, money and R, live tooltips, theme colours (auto light or  |
//| dark from the chart, colour-blind friendly switch). The lines    |
//| stay the source of truth; the box only shows what they say.     |
