/* ============================================================================
   contacts.css — Phase R5a — Contacts pane (orange identity).

   Orange is the warm sun-rise next to red Twin. Contacts are the people in
   the user's circle — warmer than the catalog Settings, calmer than the
   active Call. Liquid-glass cards. Avatar at corner narrates saves.

   All selectors live under .page-contacts.contacts-stage[data-color="orange"]
   with .c-* prefixes so we never collide with the existing .contact-* and
   .contacts-* legacy CSS in app.css. The legacy classes still apply to the
   existing #tpl-contact-detail-only ringtone + chat-log surfaces, which we
   reuse inside the new full-screen card via YStage.

   Layout adapts via container queries: 1-col stacks on phones, side-by-side
   compose + list on tablets, full topbar on desktops.
