/* ====================================================================
   DoLittle Technologies — main.css  (GLOBAL DESIGN SYSTEM)
   --------------------------------------------------------------------
   Single source of truth for the design language used by the reference
   pages:  resources/views/layouts/header/company/*

   These classes previously lived in style.css AND were duplicated across
   coaching-erp.css, college-erp.css, schoolerp.css, preschool_erp.css,
   pta_page.css, dolittle_cms.css, contact.css (each redefining
   .section-tag / .section-title / .why-card / .feature-card / .cta-section).
   main.css consolidates them so every page can share one definition.

   Load order (header.blade.php):
     1. style.css            (existing global theme: top-bar, nav, footer)
     2. main.css             (this file — consolidated design system)
     3. responsive-fixes.css (breakpoint overrides, loaded last)

   Values copied verbatim from the reference so existing pages are
   unaffected; new/refactored pages rely on these instead of re-declaring.
