 * VECTIS LAW — Shared Stylesheet
 * ================================
 * Single source of truth for all design tokens, base styles,
 * and reusable components across the site.
 *
 * Page-specific styles live in <style> blocks within each HTML file.
 *
 * Consistency decisions locked here:
 *   - Nav order: Advisory & Expertise | Fractional GC | Experts | Engage
 *   - Wordmark SVG: VECTIS at x="45", gold rule x1="210" → x2="795", LAW at x="895"
 *   - terminal-header-text: var(--cognac)
 *   - terminal-cursor: var(--cognac) block, 0.5em × 0.75em, 1s step-end
 *   - serif-accent: var(--gold)
