/* ============================================================
   DormantIQ — Reactivation Intelligence
   Aesthetic: premium dark editorial. Near-black charcoal field,
   a single confident violet accent, lime + warm-amber used only
   as quiet signals. Oversized Archivo headlines, a Fraunces
   italic for editorial accents, calm Hanken body, monospace
   reserved for small telemetry labels. Flat, architectural,
   border-led — no SaaS glow, no aurora, no template card grids.
