/* ============================================================
   IbiraPay — shared theme. Single source of truth for palette,
   type, and the components reused across pages (buttons, footer,
   tools hub cards). Change the accent in ONE place: the --accent*
   tokens below. Alternative accents are listed under :root.

   Fonts (Inter + Space Grotesk) are self-hosted in /pages/fonts/ (latin +
   latin-ext, variable weight, OFL). No third-party origin on the critical path
   and none in the CSP. font-display: swap shows the system fallback
   (--font-body/--font-display) until the woff2 arrives.
