/* Unified button system — single source of truth for all CTAs.
 * Token-based (CSS custom properties), Stellar-style.
 * Replaces ad-hoc styles for .hero-cta, .nav-cta, .see-all-btn, .offering-cta, etc.
 *
 * Usage:
 *   <a class="btn btn-primary">...</a>      Filled, navy bg
 *   <a class="btn btn-secondary">...</a>    Outline, navy border
 *   <a class="btn btn-ghost">...</a>        White bg, light border
 *   .btn-sm   → smaller (nav, cards)
 *   .btn-lg   → larger (hero)
