/* ---------------------------------------------------------------------------
   O.I.I public site - shared stylesheet (Phase 7)

   Palette is sampled directly from logos/oii_3_badge.png rather than eyeballed,
   so the site and the badge are literally the same greens:

     #0A0F0D  outer background   (53% of the badge's pixels)
     #0D1A14  badge interior     - used here as the surface/panel colour
     #00FF9C  primary accent     - the O.I.I glyph
     #00ED8D  border stroke
     #00BD64  the deep end of the glyph's gradient
     #EAFFF6  the sparkline      - used here as body text

   NO BUILD STEP. public-site/netlify.toml publishes `public/` as plain files
   with no bundler, which is deliberate: the marketing site should never be able
   to break a deploy that the Discord interactions functions also ride on.
   Plain CSS, one stylesheet, no framework.
