   SetYourPlan: design system
   Light "paper", the plan studio's look on every page: ink and greys for text, one accent (cobalt) for focus,
   links and the main action, numbers in mono. Plan-line colours appear only as small markers that match the
   lines on the studio chart (cobalt = trigger, red = stop, dark red = emergency stop, green = target, amber =
   second buy). Solid line = an order resting on Binance; dashed = checked by SetYourPlan on every candle close.
   The studio's own components (chart, rule sentences, plan card) are in studio.css, loaded on every page.
   Everything lives in stylesheets because the Content-Security-Policy forbids inline styles.
