/**
 * Front-end widget styles — South Delicious Catering Assistant.
 *
 * Aesthetic direction: refined luxury catering. A premium white surface, a deep
 * elegant green as the primary, and a gold accent used sparingly as hairlines
 * and highlights. Depth comes from soft, layered shadows and subtle gradients
 * rather than flat fills; motion is calm and orchestrated rather than busy.
 *
 * Engineering notes:
 *   • EVERYTHING is scoped under #sdca-widget so the widget cannot leak styles
 *     into — or inherit surprises from — the host theme. We also reset the few
 *     properties (box-sizing, font, line-height, etc.) that themes most often
 *     set globally, so the widget looks identical across sites.
 *   • Colours are driven by CSS custom properties that PHP injects inline on the
 *     root (--sdca-primary / --sdca-accent / --sdca-surface). The stylesheet
 *     itself is static and fully cacheable; re-theming never requires new CSS.
 *   • No external fonts are loaded. To honour the PRD's "fast loading / SEO
 *     safe" requirement and to avoid third-party privacy concerns on the host
 *     site, we pair an elegant available serif (for the brand) with a clean
 *     system sans (for body), achieving a refined look with zero network cost.
 *   • A prefers-reduced-motion block disables non-essential animation.
