/* ═══════════════════════════════════════════════════════════
   PlaySparks — marketing site
   Design system pulled from the Figma marketing frames
   (node 103:3252 collapsed FAQ · 115:3913 expanded FAQ).

   Two layers, mirroring Theme.swift:
   1. Primitives — the raw palette, named by hue.
   2. Semantic  — role tokens that alias a primitive. Only these
                  are used below, so a colour change happens once.
   New tokens created for the marketing site (not in the app
   library) are flagged  NEW .
