/* =========================================================
   CAST - shared stylesheet (used by landingpage, corporate,
   and americandiploma apps).
   Brand colors from the CAST logo family:
     - Neutral gray/charcoal : shared brand wordmark color
     - Blue accent           : American Diploma (castlogob.png)
     - Orange accent         : Corporate Training (castlogoo.png)
     - Green accent          : Landing page / shared brand (castlogo.png)
   Responsive tiers: >=1300 full desktop nav | <=1299 collapsed nav
   (covers laptop/tablet/phone with the same clean toggle)
   681-860 tablet | 481-680 large-phone | <=480 phone

   v2 notes:
   - Fixed navbar-menu gap bug: a later .navbar-menu rule (mobile/
     collapsed state) was setting gap:0 and it was never restored
     inside the >=1300px desktop media query, so nav links rendered
     with no spacing between them. Fixed below.
   - Added self-hosted-safe Google Fonts import so --font actually
     resolves to Poppins even if the host page forgets the <link>.
   - Introduced a small spacing/shadow/radius scale for consistency
     across cards, buttons and sections.
   - Softened & layered shadows, refined hover/focus states, tightened
     heading type scale, added accent-color to native form controls.
   - No class names were renamed and no selectors were removed, so
     existing markup across all three apps keeps working unchanged.
