/* --- Lines of Influence — a paper-catalog field guide to ideas. --------
   Inherits the full token set + .panel/.btn/.chip-button/.eyebrow/.hero
   components from styles.css (same override pattern as the main page: no
   :root edit, body class scoping only).

   The graph itself is the one earned flourish on this page: era hues are
   information (each ring color is an era key, labeled in the legend and
   repeated as text everywhere), Honey-deep marks selection and traced
   lineage. Everything else stays hairline-on-paper.

   Since the merge into the main page this sheet only carries the graph view's
   own components; shell chrome (topbar/tabs) lives in styles.css. */
