/*
 * TNPayoff — interactive options payoff diagram (pairs with assets/js/payoff.js)
 * BullBridge News
 *
 * Colours, radii, shadows and fonts come ONLY from the site token contract
 * (--bg … --font-num); every token has a dark fallback so the tool also works standalone.
 * All selectors are prefixed .pf- ; the surrounding UI is RTL, the chart itself is LTR.
 * Accent: sliders/tints follow the nearest [data-accent] (e.g. academy violet), else --brand-2.
 * Every rendered label is ≥ 12px (the SVG is drawn at container pixel size).
 * Variant: add class "pf-compact" to the host for a lean card (chart + 3 key metrics + its controls).
 * Inside editorial text (.prose h3/h4/p/ul/li…) the tool keeps its own type: every element rule that such
 * wrappers also set is written as ".pf .pf-x" (0,2,0), which outranks ".prose h3" (0,1,1) and ".prose li + li" (0,1,2).
