/* ==========================================================================
   Bilingual Early Educators Alliance — Stylesheet
   Design system: tokens → base → layout → components → pages → utilities

   Direction: warm, rounded, spacious "modern early-education" layout
   (oversized type, pill buttons, organic shapes, soft pastel panels)
   built for a professional nonprofit audience — not a childcare site.
   Palette = the brief's sage / pale-yellow / cream system, with the
   organization's real logo navy and green used for text and the
   primary brand accent so the site still reads as *this* org's site.
