/* ================= WEB TOKENS =================
         Derived from the v0719 app canon (single warm action accent + neutral base):
         - --accent (#F6B54B amber gold) appears ONLY on primary CTAs and true hero moments.
         - --kicker (soft amber) is the ONE secondary hue on the web: section kickers,
           small glows. No per-section hue coding — blue/purple stay inside the
           app screenshots as data colors.
         - Surfaces are neutral-warm (matching the app's #16161b family), not
           blue-gray, so real app screenshots sit inside them without a
           temperature clash.
         - No external fonts: system stack renders SF on Apple devices and
           degrades safely where Google Fonts is unreachable (mainland China). */
