/* ==========================================================================
   Pull People — Public Form
   Canonical presentation for public-facing forms.

   Ownership:
   - Theme: shell, fields, states, CTA and responsive presentation.
   - Form-specific namespaces: behavior and fields unique to each form.
   - form-privacy-notice.php: independent privacy component.

   Diagnostic keeps its diagnostic-* behavior hooks during migration.
   New public forms must consume pp-public-form* rather than diagnostic-*.
   ========================================================================== */

/* Canonical section anatomy: narrative at left, form at right.
   Home Diagnostic and Contact share this layout while keeping their own
   semantic headings, copy and processing. */
