/* =========================================================================
   FaultReady Systems — app surface dark theme (Phase 3).
   Used by: login.html, set-password.html, report.html, ward.html,
            dashboard.html, reports.html, subscribe.html,
            admin.html, secure-ops-admin.html, sticker-preview.html.

   The intent is visual only. Class names that JS depends on (per-page) MUST
   be preserved on the existing markup. This stylesheet styles the dark
   register and ships generic form, table, badge and modal primitives.
   Page-specific tweaks stay in each page's <style> block.

   Tokens come from assets/css/site.css; load that first.
