{# Inner modal template - do not use directly, use modal_base.html instead #}
{# Enhanced with animations, focus trap, and loading states #}
{% comment %}
ACCESSIBILITY FEATURES:
- Focus trap: Tab/Shift+Tab cycles through focusable elements within modal
- Home/End keys: Jump to first/last focusable element
- Escape key: Close modal (configurable via close_on_escape)
- aria-modal="true": Indicates modal dialog semantics
- aria-labelledby: References modal title for screen readers
- aria-describedby: References modal body and subtitle for description
- Automatic focus: First focusable element receives focus on open
- Focus restoration: Focus returns to trigger element on close (handled by parent)
