/* ─────────────────────────────────────────────────────────────
   site.css — Aion New Media shared styles
   Loaded on every page via _Layout.cshtml.

   Contains:
   1. Site chrome — nav, footer, go-to-top, terms modal
      (moved here from _Layout.cshtml — unchanged, static CSS)
   2. Shared page components — reused across 2+ pages, previously
      duplicated per-page with a page-prefixed class name
      (e.g. .btn-pf-primary, .btn-sv-primary, .btn-ab-primary
      all merged into one .btn-primary here)

   Page-specific CSS (hero sections, grids, unique layouts) stays
   in each page's own <style> block — only genuinely shared rules
   live here.
