/* ============================================================
   SCREEN: STATS & GOALS  (#screen-stats)
   The dashboard — a sellable, world-class surface for the feature-rich
   reading data. Everything here ELEVATES the reparented #statsBlock markup
   (today total, goal hero, pace chart, breakdown, history) into the enrapt
   design system rather than re-inventing it: stats.js tags the existing nodes
   with .ds-card / .ds-seg / .ds-track / .ds-figure primitives (defined in
   components.css); this stylesheet composes + tunes those for the larger,
   calmer dashboard context.

   Brand = "the joy of reading": warm, candle-lit library. Espresso surfaces,
   parchment ink, ONE candlelight-amber accent, forest green for on-track/ahead.
   ENCOURAGEMENT RULE: never red for "behind pace" — muted gray. Red = errors.

   Mobile-first (390px). Tokens only — no new palette, no new fonts.
   Every rule is scoped under #screen-stats so nothing leaks to sibling screens
   that share the foundation/component surfaces.
