   Andexa — sovereign AI analytics. Light-first "porcelain vault".
   Porcelain ground, deck-navy ink, brand teal #0FA293, gold only
   on medals, one dark island: the product console.
   One sheet serves index.html (LTR) and ar/index.html (RTL)
   via logical properties; html[lang="ar"] swaps the type stack.
   Shape rule: shells 28px, cores 22px, interactive pills.
