/* buttons.css — Global button styles
 *
 * All button and CTA link styles.
 * Per FONT_SPEC: DM Sans 500, uppercase, letter-spacing 0.06em, 13px.
 *
 * Variants:
 *   .btn--primary   Gold background — primary action, works on all backgrounds
 *   .btn--secondary Outlined green — secondary action on light backgrounds
 *   .btn--ghost     Transparent, white text/border — for dark backgrounds
 *
 * Dark-background ghost overrides are applied in header.css and final-cta.css
 * since the ghost button renders on both dark and light backgrounds.
