/*
 * CHOA (Children's Healthcare of Atlanta) brand palette, pulled from choa.org's live
 * stylesheet: primary green #00a94f, deep green #285844, blue accent #0081c6/#005da4.
 * Variable names kept as teal-*/blue-* from the original palette to minimize the diff,
 * but the values now match CHOA's real brand colors.
 *
 * Font: CHOA's site uses "GothamRounded", a commercially licensed typeface (Hoefler &
 * Co.) — not something we can bundle here. "Poppins" (Google Fonts, free) is used as a
 * similar rounded-geometric sans-serif stand-in for the demo's look and feel.
