/* =========================================================================
   SENTIRA — AI Voice-of-Customer Intelligence
   Design system: warm, human, editorial. Violet + coral, Fraunces serif
   headings, genuine light/dark section mix (not all-dark like Evalio, not
   Fundari's rhythm). Every section is its own distinct component — no
   card-grid/spec-row/roster-row patterns reused from the other two sites.
   Mobile nav follows the proven-safe pattern: plain display toggle only,
   explicit height, no transition/animation on the show/hide itself.
