   Page styles for /yazilim/dijital-donusum (Dijital Dönüşüm).
   Foundation (tokens, base, type, buttons, chrome) lives in tokens.css + site.css.
   ADDITIVE ONLY — nothing here overrides the global foundation. All colour comes
   from tokens; light/dark handled automatically. Teal is scarce: hero tick,
   process numbers, one comparison accent-rule, CTAs.
