/* Hanetic Design System — base.css (Phase 1)
   ------------------------------------------------------------------
   Reset, page scaffolding, and the shared Hanetic shell (site header).
   Works with shell.js which toggles `shell-compact` / `shell-peek` on
   the <html> element. Dark-context shells (portal/cars) are re-tinted
   in their theme files; this file owns geometry + safe-area only once. */
