 * File Name: notification_template_enrichers.data.js
 * Type of Program: Data / Registry
 * Description: Admin-edited notification templates are plain text — no
 *              conditionals or expressions allowed. Any type that used to
 *              branch on data in JS (e.g. task_overdue's singular/plural
 *              wording) gets that branch precomputed here into flat
 *              placeholder keys BEFORE substitution, so the stored title/
 *              message only ever needs straight {{key}} swaps.
 *              Mirrors data/email_template_enrichers.data.js.
