/* ============================================================================
   PlugPHP — app.css
   Design system implemented from "PlugPHP UI.dc.html" (Claude Design).
   Developer-minimal, high-contrast, light theme. Two restrained accents:
   Plug Purple (#617CBE) and Token Green (#10B981).

   CSP-safe by construction: same-origin stylesheet, no @import of external
   fonts (uses a system stack), no inline scripts needed (mobile nav is
   pure CSS). Works with core/View.php's Content-Security-Policy.
