/* ============================================================================
   ROUTE C — "Three Depths"
   Regulated nervous-system aesthetic. Soft, contemporary, breath-paced.
   Person-first warmth leads. Energy from confident scale + a slow breathing
   rhythm; calm from a settled sage/sand/clay palette and generous space.

   Intended production type (swap to self-hosted .woff2):
     Display : a warm humanist face with calligraphic stress, NOT a neutral
               grotesque (e.g. Optima / Marat Sans / GT Flexa) — editorial and
               calm, deliberately un-"SaaS". Prototype leads with Optima (macOS).
     Accent  : an italic serif for human/personal lines (e.g. Tiempos Italic)
