/* ============================================================
 * BaZi Atlas — shared design system
 *
 * Loaded before each page's own <style> block, so page-specific
 * rules always win. Contains only what more than one page uses:
 * design tokens, reset, body, nav, hero, typography, layout,
 * form controls, result shell, prose/tables, footer.
 *
 * Page-specific component styles stay inline in each page.
 * Extracted 2026-09-17 from the duplicated inline blocks of
 * index.html and ten-gods-calculator.html (which had already
 * drifted apart by a few pixels); those pages now link this file.
