/**
 * Legacy Log — ll-core.css  (v3.8.0)
 * ONE source of truth: fonts, design tokens, base typography.
 * Warm, calm SaaS. Thin lines, soft shadows, gentle glows.
 *
 * Load order (every surface):  ll-core.css → ll-ui.css → page styles
 * Legacy variable names (--ud-*, --t1, --primary-gold …) are bridged at
 * the bottom so older page styles inherit the new palette automatically.
