/* V217 - Task detail & task form visual redesign.
   UI-only, additive, scoped under .task-detail-v217 (task_detail.html)
   and .task-form-v217 (task_edit.html). No routes, permissions, data,
   or workflow logic are touched here — only presentation of values
   already rendered by the templates. */
