/* ============================================================
   core.css — dotshock.ai v3 FOUNDATION (single source of truth)
   ------------------------------------------------------------
   The shared base for ALL three templates:
     • SITE  (shock.css + pages.css / services.css)  — marketing + suite landing
     • APP   (suite-app.css + suite.css + per-app)    — the .shock Suite apps
     • ADMIN (admin.css)                              — admin / backend pages
   Owns: @font-face, design tokens (:root), reset/base, layout primitives,
   the editorial frame motif, and the button system. Change brand colour,
   type, spacing or motion HERE and it propagates everywhere.
   Managed from the `design` branch — feature branches consume, never redefine.
   No external font CDNs. Self-hosted woff2 with strong system fallbacks.
   ============================================================ */

   The page renders perfectly with system fallbacks even before the owner
   supplies font files. font-display:swap avoids invisible text. */
