/* ============================================================
   ZuckZapGo Dashboard — Shared UI components
   Spec: .claude/specs/001-dashboard-sprint-1/  (Sprint 1)
   Governance: .claude/CONSTITUTION.md §3 perf, §4 a11y, §7 dark mode parity.

   Loaded by index.html AFTER css/app.css so token variables (declared on
   :root in app.css lines 1–13 for light; lines 2011+ for dark) are
   already in scope.

   STRICT RULES (NFR-005):
   1. No raw hex / rgb / hsl outside of :root token assignments.
   2. All colors use var(--…) referencing app.css tokens.
   3. Dark theme inherits automatically — no `.dark { ... }` overrides
      needed here; the variables already flip in app.css.
   4. Each component scopes its rules under a unique prefix
      (.zz-ui-toast / .zz-contact-picker / .zz-data-table / .zz-confirm-dialog)
      so it never collides with Fomantic UI 2.9.4 or jQuery defaults.

   Section index:
   §A — Local component tokens (computed from app.css tokens)
   §B — .zz-ui-toast     (Task 1.1)
   §C — .zz-contact-picker (Task 1.2)
   §D — .zz-data-table   (Task 1.3 — appended below)
   §E — .zz-confirm-dialog (Task 1.4 — appended below)
