/* ============================================================
   PAYAED — INSIGHTS
   Editorial / print-derived layer for the Insights index + the
   long-form article template.

   Consumes tokens from css/style.css :root — never redefines them.
   Works under body[data-theme="light"] (cream bg / ink fg / maroon
   accent) for articles AND under body.page-insights[data-theme="dark"]
   for the index grid.

   Token map (old -> new):
     --hairline   -> --line
     rgba(brick)  -> color-mix(... var(--brick) ...) / var(--accent)
