/* ============================================================
   EHR Mirror — Unified data-browser navigation
   Conceptual neighbor: cross-page navigation (the section
   switcher rendered above every EHR mirror page).
   Loaded by: templates/base/bundles/css.html (always — the
   nav partial is included on every EHR mirror page, so the
   stylesheet ships in the global bundle).
   Consumer: templates/ehr_mirror/partials/_ehr_nav.html
   plus the patient banner / "view all" link helpers used by
   patient_detail.html.

   Visual language deliberately mirrors the chip strip in
   ehr-mirror.css (same radii, borders, shadow) so the nav
   reads as a sibling of the filter bar instead of a separate
   paradigm.

   BEM:
     .ehr-nav                       — outer card
     .ehr-nav__group                — one labelled section
     .ehr-nav__group--active        — section containing the current page
     .ehr-nav__group-label          — "Directory", "Activity", etc.
     .ehr-nav__links                — flex row of pill links
     .ehr-nav__link                 — individual link
     .ehr-nav__link--active         — currently-rendered page
     .ehr-detail-viewall            — "View all in browser →" link on
                                      patient_detail section headers
     .ehr-patient-banner            — "Filtered to: <patient>" banner
