/* =============================================================================
   LernBro Design System — "Dark Neon, Professional"
   -----------------------------------------------------------------------------
   A production-ready theme for a Swiss ADHS learning platform (grades 1–9).
   Warm, trustworthy, kid-friendly — with restraint, hierarchy and breathing room.

   PRINCIPLES
   1. Elevation over glow    — depth comes from layered near-black surfaces,
                               not from neon glow on pure black.
   2. Pixel font is an accent — 'Press Start 2P' appears ONLY in the logo and
                               the occasional big level/number. Everything else
                               uses Plus Jakarta Sans (a warm geometric sans).
   3. Purposeful colour       — neon is a semantic/accent tool, not a coating.
   4. One spacing scale        — everything sits on a 4px baseline grid.
   5. Clear hierarchy          — a single type scale drives every heading & label.

          Google Fonts are @imported below; no build step required.
