/* Trading Journal — shared design system.
   Visual language adapted from the TradeLog dashboard reference: dark-first
   layered surfaces, Syne for headings/UI, DM Mono for every number, thin
   hairline borders, 14px radii, gradient-topped stat cards, sliding toasts.
   Light theme is the same system re-toned (green/red darkened so they stay
   legible on white — the reference's #00d68f only reaches 3.07:1 there).
   No build step: plain CSS. See assets/js/theme.js (toggle + nav + toast)
   and assets/js/charts.js (Chart.js PnL curve). */
