/* LP3I Referral Voucher System - Global Styles */

/*
 * LP3I corporate design tokens. Raw brand teal/rose (~3.3:1 vs white) are
 * kept for large/decorative use only (accent bars, icons, borders) - solid
 * buttons/badges use the "-dark" variants below instead, chosen so every
 * pairing clears WCAG AA (>=4.5:1 for text, checked against relative
 * luminance). WhatsApp's own brand green and the generated voucher PNG's
 * colors are deliberately left untouched - see project notes.
