/* ==========================================================================
   Kobolabs Limited — Stylesheet
   Design language: a warm paper background with a single deliberate accent —
   burnt copper, drawn from the kobo coin. Dark warm ink instead of pure
   black. A muted deep green ("bush") is used sparingly for links and small
   secondary accents. Left-aligned, editorial grid; hairline dividers rather
   than card shadows.
