defmodule MvWeb.CustomFieldValueLive.Index do
  @moduledoc """
  LiveView for displaying and managing custom field values.

  ## Features
  - List all custom field values with their values and types
  - Show which member each custom field value belongs to
  - Display custom field information
  - Navigate to custom field value details and edit forms
  - Delete custom field values

  ## Relationships
  Each custom field value is linked to:
  - A member (the custom field value owner)
  - A custom field (defining value type and behavior)

  ## Events
  - `delete` - Remove a custom field value from the database

  ## Note
  Custom field values are typically managed through the member edit form.
  This view provides a global overview of all custom field values.
