/* ═══════════════════════════════════════════════════════════════
   Advantage Gold chart core — shared chrome for every chart card.

   One engine, three renderers (see chart-core.js):
     milestone  — sparse readings with a labelled strip beneath
     series     — dense time series with callouts and stat pills
     projection — the parametric cash-vs-gold calculator

   Everything sizes in em off a 1cqi root, so a card is resolution
   independent: the same markup renders as a 2000px poster for the
   PNG export and as a phone-width card, with one breakpoint that
   restacks rather than shrinks.
