/* ============================================================================
   AGTA Sports Academy — bespoke public site (agta.ewizpro.com showcase build).
   Self-contained. Brand: navy #12325a + clay #c1502e. Poppins (house font).
   Light by default (house S4.2); .dark via [data-theme=dark]. Bilingual EN/中文
   is pure-CSS: html[data-lang=en] hides [lang=zh] and vice-versa (both in DOM
   for crawlers). No brand image assets — CSS gradients + emoji only.
