/* ==========================================================================
   NAVERA — "Trajectory" Design System
   --------------------------------------------------------------------------
   Derived from the logo: a navy "A", two rising arcs (teal + amber) and a
   spark at the tip. Everything here builds on that idea:
     • Navy  = depth / trust         • Teal  = technology / signal
     • Amber = the spark / action    • Paper = calm, readable surfaces
   Signature motifs: rising arcs, the spark glyph, mono "coordinates" labels.
   All classes are prefixed with `nv-` so they never collide with the legacy
   course pages that still load style.css / index.css.
