/* ===========================================================================
   doubles.singles — Shared design system stylesheet
   ---------------------------------------------------------------------------
   This file is the single source of truth for:
     · Design tokens (colors, type, spacing, radius, shadow)
     · Base typography
     · Nav + Footer (identical on every page)
     · Button system
     · Eyebrow / section-head / container / hairline patterns
     · Tennis-ball + court-line decorative primitives

   Page-specific styles (hero, event card, Volley spotlight, etc.) live in a
   <style> block on each page, but ALL of them inherit the tokens below.

   Import order on every page:
     1. Google Fonts (Cormorant Garamond + Hanken Grotesk)
     2. This file
     3. Page-specific <style> block
